Each day after school I check my boys' daily behavior report that their teacher has filled out. If it has a green circle, that means they were well behaved, or at least they weren't caught when they were misbehaving. If it has a yellow circle, it means they got a warning but it wasn't too serious of an offense. If there is a red circle, I know they did something pretty bad and I usually have to call their teacher.
When my older son was in kindergarten he normally got green circles so I was suprised to see a red circle one day. I noticed that his teacher had written down that it was for bothering a classmate. I asked him, "So, Alex, who did you bother at school today?" He said, "I don't know Mommy." I thought he was avoiding the issue so I asked him again, "Who were you bothering?" He answered again that he didn't know. I decided to change the question and see if he would tell me at least what he had done. He answered, " I hit him with my folder but I don't know who it was." I was starting to get annoyed so I asked him a final time who he had hit. He said "Mommy, I don't know if it was Rodrigo or Medardo!" Oh. They were the identical twins in his class.
