It happened a few times when I used to go to pubic school, I was accused of drawing on the wall and on someone's face in first grade. Only that I was on the complete opposite end of the classroom and playing with blocks, not crayons.
Then it happened again in second grade with these people chasing my friend and it got me pulled into the argument. I only ran along side my friend asking why she running from them and what was happening, I had nothing to do with whatever fight broke out. The teacher knew I wouldn't do anything like that though, so she saved me from the recess monitors. I still don't know what caused these random people to chase my old friend to this day, they "claimed" that she refused to be their friend, but that's no reason to chase her in the first place even if that was true.
Do you have any family traditions?
