I noticed that I will pretty much chat up anyone on the playground- from other moms, to grandmas, to babysitters, with one notable exception: I won't strike up a convo with good-looking dads unless their wives are there.
Because they get this smug look in their eyes, like "Oh, she wants me. Not only am I totally hot, but I'm here with my kid which totally makes me look like a total catch! Every mom here totally wants a piece of this!"
Okay, maybe that's completely my imagination.
Still- hot dads? Not gonna touch them.
