Twilight laid on her bed, curled into a ball. Every second was pain, every moment was discomfort, and every hour was misery. To put the cherry on top of this affliction, her hormones were running wild and everything made her upset.
You guessed it - her period. Once a month, a girl's body will prepare her for getting pregnant. If an egg is not fertilized, it will be discharged from the body along with all the built-up tissue. Most women, like Twilight, get tormenting cramps. Oh fuck, they hurt.
Now, Spike is obviously not a female. He'd never had a period. He hated it when Twilight menstruated because it meant about a week of work with no help from her. Plus, she'd cry a lot. A lot. A lot. Anyways, so Spike was getting tired of this. It annoyed the shit out of him. This month, he was prepared. Spike was going to annoy the shit out of her instead.
"Hey Twilight. Hey Twilight. Hey hey hey Twilight." He began.
"Don't say hey four times." Twilight scolded. "It reminds me of hay and I'm on a diet!" She then proceeded to start crying.
"What did I do?" questioned Spike.
"Don't you fucking start, Spike. You know I'm on my period!" She blubbered.
"Can't you just get over it? I have to work the library all week by myself, thanks to your stupid cycle!" Now, Twilight flat-out began bawling. "WAAAAAAAAAAAAAAAAAAAHHHWAAAAAAAAAAAAAAAAAAAAAHHHHH!"
At this point, Spike left the room, calling behind him,"PERIODS AREN'T EVEN THAT BAD!" There, that should do it.
