In 3rd grade we had a rack of books in the class and we would sometimes be given half an hour to pick a book and read, I was a reader, I got like half way through a book and it was time up and we had to put the books back, well I wanted to finish it so I put it in my bag and went to ask the teacher if I could finish it later, she was busy talking to someone and told me she would talk to me "in a minute" and like a 7 or 8 yo I promptly forgot about it. An hour later she sees the book in my bag, calls me out in front of the whole class for stealing and when I tried to tell her Id tried to ask if it was ok to take it home so I could read it later but she was busy she called me a "liar and a theif" and back onto the shelf it went.
A few days later I took the book and hid it behind a cabinet near the door to our room, at reading time she noticed it was missing, demanded to know what Id done with it, accused me of stealing it again and tipped my bag onto the floor to find it. When she didnt find it, she told me "once a theif always a theif" and when the bell rung that day and she was busy packing up her desk, me the last kid out the door put his bag down to tie his shoe... and I stole the fucking thing.
If you're going to treat me like I'm guilty anyway, might as well be guilty.
