Why do i have hooves?

I watched as a pony I had never seen before wheeled in a tray which I think has breakfast on it. Her mane was red, and she had pink fur, and she was a unicorn.

"Hi there! My names Strawberry Fizz! We are going to talk today!" She said in a syrupy type voice.

"Bloody hell they got me a therapist!" I whispered under my breath. Shit, she overheard, I watched her eyes widen.

"Young ponies like you should not be using swear words!" She said shocked. "Now go on and eat your food!"

I looked at the salad on the tray and the sandwich. The salad has daisies in it..... I also picked up the bread off the sandwich. Hay... HAY!?! Who puts hay inside a sandwich? HAY! Disgusting! And the milk shake or smoothie or whatever it is is green! I suddenly wasn't hungry anymore.

"Is there something wrong with the food?" Strawberry asked me concerned.

"I'm not hungry." I replied and watched her horn start glowing. The sandwich got lifted up as I watched confused.

"Young growing ponies need their energy." She said sternly as she force-fed me the sandwich was surprisingly good so I let her since I was pretty much starving since I had not eaten the day before.

"AGAIN with the young pony. I am not young NOR A PONY! Can you ponies not grasp that subject?" I scream at her

She looks worried. She probably thinks I'm about to have a tantrum. Well i'm not. I'm just pissed off because they think I am a child. Her face returns to normal, and she starts asking me questions, most of which I cannot answer like, "Do you know where you in Equestria you lived?" I just said I don't know  to most of it which gave her the assumption that something terrible happened and that I don't want to remember. Well, nothing happened. I ask to go to the toilet, and she is about to come in, but I stop her. I stare at the toilet. How do I use that?... I try a few positions until I finally figure it out. I wash my hooves in what I guess is an equine sink and examine myself in the mirror and to waste time mess up with my mane, as I don't want to speak with the therapist much.

I guess I spent too much time in there as she comes in catching me messing up my mane. She looks at me in a weird way and herds me out of the bathroom, handing me a strange object. I stare at the object confused. She looks very surprised I don't know what it is as Strawberry takes it from me and shows me how to use it. It's a comb. Well she could have just told me! I thought. Eh what the heck though, I've got nothing better to do with my time so i take the comb and brush my hair as I listen to her.

"Guess what!" she asks with a big grin.

"What?" I ask in an annoyed tone.

"You're getting a foster family! That means a nice family is going to take you in!" She says cheerfully expecting me to be happy.

"I'm eighteen, I don't need to be fostered, I'm a perfectly mature adult that can take care of myself." I reply bitterly.

She looks at me sympathetically. "Hun, I know that some bad things might have happened to you in the past, but you got to let this being a human young adult stuff go! Now come on and lets meet your foster family!" She says gently. Okay lets get this over with, I roll my eyes and walk after her hesitantly wincing when I put weight on my broken leg. It felt better already though . Whatever they put on my leg was great!
