I guess I'm getting a bit more brave...
Today I came into my college wearing a mickey mouse t-shirt and black and green fingerless gloves(sort of a weird quirk of mine to wear fingerless gloves) and because of my condition I did slur in my speech a bit today. I usually bring a My Little Pony Notebook to class as well and I had a green and black zebra stripe ribbon in my hair.
Well, my "mature" classmate(who ended up disrupting the whole class later on, hypocrite) looked at me /very/ sternly and asked "How old are you anyway?" loud enough for the whole class and /my instructor/ to hear it.
You would think that I would get all upset and cry, but...well...I guess I've had enough. I turned to her with a mischievous smirk, looked her right in the eye and said "I think I'm 23 but I dunno...you should ask my stuffies and the pink blanket on my bed. Well, one thing for sure...I'm definitely older than your momma was when she had you..."
She just rolled her eyes, scowled, and muttered "f**ing weirdo..." and I just sat there and thought....BURN!! Vengeance at last!
