There was the fecal graffiti issue in the men's room at the library, and there was the time some friends with a blended family of two toddlers smeared shit all over everything in their bedroom because they were "painting..."
I don't think I want kids.
Urgh, that is not any kind of painting I would want to be a part of.
You might be right in the wanting kids category, there are definite downs to the ups!!
