As her punishment, we made her write a letter to her teacher apologizing. We told her that we weren't sure if we were going to make her give it to her but that she did have to write it.
Here's what she wrote..all by herself:
Dear Ms. Barnes,
On Thursday I made a burp during recess while I was in with you and some other kids. If you heard it , I'm sorry. If you didn't hear it I'm still sorry. I don't really think I'm a girl who would do that anymore.
