Foxfire and Gotta Know, from what I've heard about dog people, there is nothing to worry about. The same thing applies to them that applies to BF -- if you're respectful, you will be fine. No worries for your husband or those kids, Foxfire. It can be tricky, trying to keep your cool when you hear something you're not accustomed to hearing, for sure; but if you can try to discipline yourself not to freak out, you usually discover there never was anything to freak out about to begin with. (Even if there was some pointed message being delivered, you just say your apologies and turn around and go a different way.)
Gotta Know, I'm the same way. Not afraid, but I sure do keep my eyes and ears open. It's so cool, because there's almost always something of interest to see and hear.
