they're expensive, too

Sometimes, when I see my husband and his twelve year old sister playing together, I feel pretty guilty about not wanting kids. He'd be a fantastic dad: really fun and patient and hands on.
Then I remember that I teach children for a living, and at the end of the school day, want nothing more than to be away from children and around adults. Then I feel OK again. He doesn't really want to be a dad anyway. Too much work.
