Cool. :) I hope you sister is dealing with that well. The unspoken discomfort can be worse than just saying "I hate you".
Lucky for me, my mom came from a non-theist family and was able to knock some sense into my dad. Most of my headache came from the surrounding area. My family was actually completely tolerant.
Ah, Atlanta is nice. I've traveled lots, but I've always lived within an hour or two of this place.
My partner (teaches early ed. music) is getting a position in Orlando, so we plan on being there next year. DISNEY WORLD! :)
