Anti-Social Germs

I just noticed a very old note that I'm not sure if I blogged about or not,
In my big boy's first year at preschool, I taught him to was his hands every time he came home.
He didn't like doing this so he asked why he had to do this everyday, I told him because there are germs at school, that's why kids get sick so often, the kids bring germs to school, they all play together and then they bring new germs home, and germs are what makes a person sick.

So for a couple of weeks I notice that every time I pick him up at school he's playing by himself, I eventually ask why I don't see him with other kids and says he's afraid of their germs.
