Remembers, but no grudges

I watch DS1 a bit today during my lunch break. He played "ring around the rosie" with a teacher and friend at daycare. It's nice that he doesn't hold a grudge, because I am pretty sure that the classmate was the one who bit him on Friday. I didn't see it happen, but when I was observing over lunch on Friday I saw this same girl push my son and another child and bite a different child. The teachers handled it as well as possible. I hope she gets over this phase soon. This morning DS1 stopped at the doorway to the classroom and didn't want to go in. The child that was closest to us (there were 4 there already) was the suspected biter. He may not hold a grudge, but apparently he doesn't forget either.
