a few days (at different times). Our house is seriously like a hotel in the summer time.
Somewhere in their stay, we always stay up having at least one good talk that starts out about our childhood and our shared experiences and it progresses from there. Yeah, I'd say I'm pretty safe for them to talk to. (Except I then post about it on-line.) And I'd say they got to tears more on their own than by me getting it out of them.
