A retarded girl.
It was a peculiarity of Anita's retardedness that she got upset very easily. You would only have to say "Hey, Anita!" to get her attention, then say something innocuous, like "It's raining!". This would cause her to scream "It's not!", start crying, and run away.
When I was about seven years old, Anita would have been about fifteen. My friend and I climbed a small flight of stairs to find her standing at the top, with her handler and a teacher (who was congratulating her on how well she was behaving that morning).
I decided that this would be a very good time for her to go mong in the head, so I yelled "Hey Anita... YOU HAVE NEW SHOES ON!"
Normally she would have said "I DO NOOOOT", cried, and run away. This time, however, she picked me up, bellowed in my face, then threw me down the stairs.
Funny folk, these mingmongs.
