Cadence approached her client's house. She's seen how a good portion of the Canterlot nobility tended to behave (including her own cousin Blueblood) and she was determined not to be like that; so she decided to be a babysitter.
Most foalsitters were for hire but since she's already loaded she's doing it for the fulfillment and good deed.

Cadence knocked on the door. Her client Writer answered. She was a blue unicorn mare with a white mane, and a quill and scroll for a cutie mark.

"Good day your highness." Said Writer.

Cadence smiled, "Please mam I'd rather not be treated like royalty while on foalsitting duty."

Cadence entered the building and found Heartache sitting on the couch. Heartache was a blank flanked blue earthpony filly with a white mane, at the age of 10.

Cadence approached Heartache and said, "Hi there. How're you doing?"

Heartache glared at Cadence and said, "None of your $@%# business."

That comment shocked Cadence, when she was her age Celestia would've been angry like nopony's business if Cedence would've said that to anypony.

Writer approached the door while saying over her shoulder, "Have fun you two. And there's corn and cabbage for my darling's dinner; or you can have anything in the fridge you want except the carrot cake, that's for the bake sale tomorrow." Then Writer left.

Heartache huffed and raised her nose up in the air, "I can't believe a pony of your stature would get a job." Heartache stepped off the couch and walked upstairs to her room.

Cadence was beginning to worry; so far this filly was being rather rude. But hay, why should she believe this filly is bad for that? Heartache could just be confused; in fact her name 'Heartache' could mean she's in a lot of pain.

Just then Heartache came down with some bits. She approached Cadence and said, "Here lady, 30 bits to go away."

Again Cadence became shocked. Was this filly seriously trying to bribe her?

Cadence lowered her head to Heartache's level, "Now now little filly, it's wrong to bribe ponies."

Heartache rolled her eyes, "Alright I'll make it 40 bits."

Cadence raised her eyebrow, "I'm not going to leave a foal home alone for something I've already got enough of."

"60 bits, and that's my final offer." Offered Heartache.

"How about instead I go fix dinner." Offered Cadence as she went to the kitchen.

Once in the kitchen Cadence opened the fridge door, she found the corn and cabbage. She proceeded to take it out and could not wait to have it.

Heartache rushed into the kitchen while shouting, "What the #$@% will get you to go away you stupid princess!"

Cadence nearly jumped. Why was this filly so desperate to get rid of her.

"Why do you want me gone so badly?" Asked Cadence.

Heartache harumphed, "I don't need a #@$% foalsitter, I can take care of myself; my mom is just so mean!"

Cadence placed her hoof on Heartache's shoulder, "Now now sweetheart, I've known your mother for years; I even remember when she was born; and I can honestly say she is a very caring mare."

Heartache's mouth gaped open, "You were alive when my mom was born? You're an old lady."

"Not when you're an alicorn like me." Said Cadence.

"How old ARE you?" Asked Heartache.

"I was born over a thousand years ago." Answered Cadence.

"HAHAHA!" Heartache began laughing hysterically.

Cadence rolled her eyes, "I'll be making dinner."

While Cadence began fixing corn and cabbage she heard the fridge door open. Cadence turned around and found Heartache digging around the fridge.
Cadence used her powers to levitate Heartache and close the fridge door.

"HAY!" Heartache was shouting while being levitated away from the fridge, "How'd you see me? You was turned around."

"It's 'you WERE' not 'you WAS' and I HEARD you open the door." Explained Cadence.

"But I want that carrot cake, mom said I can!" Whined Heartache.

Cadence giggled, "Now now, your mother herself just told me it's for a bake sale tomorrow. Don't you know that lying is wrong?" Cadence placed Heartache down on one of the kitchen chairs.

"BUT I WANT SOME!" Heartached screamed, then began to wail; she even was banging her front hooves on the table.

Cadence sighed. She enjoyed foalsitting, but sometimes she wished she'd quit.

Cadence lifted Heartache up again and carried her to her room.

Once they got to Heartache's room Cadence placed the wailing child on her bed and said, "Until you learn to behave you have to stay in your room."

Cadence started fixing the corn and cabbage. The whole time Heartache was screaming.
Cadence wondered if she was like this as a child. Then again, most foals around Heartache's age behaved better than this. It seemed like this foal was just being naughty.

Cadence sighed, not out of frustration but out of sadness. She didn't want to have bad viewpoints of others, especially children; but her friend Writer might have spoiled this filly a bit.

Later Cadence finished cooking and brought the food up to Heartache. Heartache was still throwing a tantrum.

Cadence opened the door and found that Heartache has trashed her room. Their were toys and books all over the floor, and the bed was unmade, and there was even a hole in the wall.

"Goodness kiddo, why'd you trash your bedroom?" Cadence asked.

Heartache ran up to Cadence and kicked her in her front left leg (causing her to drop Heartache's food).

"OW! That wasn't nice at all young mare!" Scolded Cadence.

"You're not the boss of me $%#@!" Shouted Heartache.

Cadence levitated Heartache up and proceeded to carry her into the bathroom. Then in a soft and kindly voice Cadence said, I'm sorry Heartache, but I can't allow you to behave this way."

Once in the bathroom Cadence placed Heartache on the sink and then washed her mouth up with soap.

"Mmh! Ack!" Screamed Heartache.

"I don't like doing this but you can't behave this way." Stated Cadence.

Cadence was finally home. She began to walk down the Canterlot halls where she came upon Celestia.

"How'd your foalsitting job go Cadence?" Celestia said just before noticing Cadence looked like a wreck.

"Oh my. What happened Cadence?"

Cadence looked up at Celestia and said, "I had the worst babysitting job EVER. Writer's filly is the most spoiled rotten brat I have ever met." Cadence then broke into tears.

Celestia placed a wing on her, "What did Writer have to say about this?"

"She had the nerve to accuse me of hurting her child. Heartache (her foal) threw a temper tantrum because I wouldn't let her eat a cake her mother was saving for a bake sale tomorrow, and in the process of the tantrum she made a huge mess in her room, she even made a hole in her wall; and when Writer finally gets home she has the audacity to accuse ME of making the hole." Cadence broke down crying.

"I...I thought...I thought Writer was my FRIEND." Choked Cadence.
