Thanks, everyone! Sorry it got locked, so I couldn't say thank you there. I understand the worry, but the info that I guess seemed headed toward something non-CD-friendly was actually fairly useful, as I'm not baptized, so it's good to know that I shouldn't wander up and take Communion. I don't go to church more than once every few years, and it's never the same faith as the last time, so I'm unaware of what parts to follow along with, and what parts to just sit and watch for. Err, so yeah. Thanks again to you all. So I guess, here are my other questions - are there any head-covering issues? In Italy, I had to cover my head in most Catholic churches. And in the Russian Orthodox Catholic wedding I was in, I was covered up to the chin, no bare skin around the neck showing. Obviously, not gonna wear my "goin' out" (ha!) outfits on Friday, but just wanted to check how restrictive it would be. Wondering about appropriate clothing - business casual/dressy should be fine, right? Again, thanks to all for the advice. She's a good friend (we've been friends for 16 years) who was there for me when my stepdad died of brain cancer, so I want to be there for her after her Dad died of the same disease. Thanks to everyone for the good thoughts and prayers. They're good people; the whole family is wonderful.
