Those who continue to be bitten will eventually bite.
Or something like that.
Avery has crossed over to the dark side. We received our first (hopefully only) bite notification yesterday. She hadn't been bitten in several weeks as the main culprit was moved to another room, but she (we'll call her Hannahbal to protect her identity) was mysteriously back this week and is chomping on everyone.
Avery apparently decided to take matters into her own hands. When the teacher handed me the bite report yesterday I said "Oh, no! Avery, did you bite someone?!" and she cackled.
So I really don't think she's one bit sorry.
