Not as I do.
How can you possibly make a 5 year-old understand that just because his father doesn't wear underwear, doesn't mean that HE can go commando too? I'm just waiting on a call from his teacher. I know it will come eventually.
I thought that I smelled victory today when I picked Gavin up from school and he was complaining that his tush was cold. "If you wear underwear, it keeps your tush warm, honey." Hmmm ... well Dad doesn't wear any and HE stays warm!
