I could ramble on though, and really I just wanted to thank you all for your stories and ideas. Dude, I loved the story about your daughter. I can just see her trying to find an adult book to read and I think that that is awesome that you are letting her try it out! I've never even thought to show the kids the adult side as our library is divided so the kids sections is in a completely different room far away from the adult books (and in fact you can't even see them when walking in). We might have to make a trip over there someday.
I think the important thing is that she arrived at this on her own initiative. So if you're thinking maybe one of yours might be ready to make this leap, I'd be sneaky about it... maybe just have them follow you to the adult section so you can pick something out for yourself, just so they notice that there's this whole other world of books over here, and then let them go from there.
Anyway, I'm glad you enjoyed the story as much as I enjoyed telling it.
