I was raised Catholic, received my sacraments, and attended Sunday school until Confirmation although I never believed and always found the whole thing pretty silly. My mom was not much of a practicing catholic although found it necessary for me to do all of that. My dad was Protestant although never attended church or anything at all.
I'm agnostic and my mom likes to act shocked by my opinions although she probably feels the same way inside or at least I like to think most people probably do.
