Jo -

Treat your faith more like a social club, particularly if you enjoy the people. I don't recommend lying, but waffling quite a bit is often a good strategy. There is so much bias on so many things in the world that waffling is a great strategy for anyone pursuing the OB life and not wanting to be a complete outcast. In fact, waffling may be a prerequisite for OB (e.g. I think you need to entertain the possibility that your friends and their faith are right as well).

Good luck!
