Maybe that is why we all work with kids? None of us like talking to adults?? LoL

For real, though; most people love to talk about themselves. If it gets awkward, and you feel you MUST make conversation, ask her questions about where she is from, what she does for a living, etc. Even better, ask her things about the kids! People LOVE talking about their kids.

And even if it's awful... it's only an hour!!
Good luck, hun!
