That said, if she knows she doesn't like working with kids then it is probably best she doesn't!
Agreed. I've had a couple other people turn us down for activities due to the age of the boys, and that's always acceptable. Some people/places just don't mesh well with a group of 6-8 year old boys. It was the several minutes of ranting about how it's shameful parents don't introduce their kids to art that had me wondering how she coped with the cognitive dissonance. And insulting my kid is a really good way to ensure I'm not inclined to do favors for you.
