Last year, when my little one was in Kindergarten, she drew her teacher a picture and put it in an envelope to give to her. Well, a note came back from the teacher with a $5 bill. It said "****** gave me an envelope with a picture she drew me that said "My Best Teacher" and it had this in there too. Just wondering what it's for." I about died laughing. The kid was paying off her teacher. I wrote a note back telling the teacher that I told my kid to stop trying to pay her off.
