Here's a Live Journal entry from five years ago.
In this corner...
...there was a nine year old boy. In the other corner was a much larger ten year old girl.
She started it by pushing him. Hard. Repeatedly.
They started hitting each other in the lobby. It ended up in the ladies room.
When I got there and opened the door they were both staring each other down, both with looks of pure hatred and anger on their faces.
Then there was the young lady who ran up a large fine by returning videos late.
'That's retarded,' she repeated several times before paying up.
Her name was Q-Tay.
