Here's one my husband faces constantly:
On business trainings or conferences (he travels quite a bit), there are always planned evening events where everyone drinks heavily. He doesn't drink, but has felt pressure because eveyone is holding a drink the entire time and they make teasing comments about him for not having a drink. This also happens with clients at dinners.
I prayed constantly for my husband's well being and safety on a recent trip, and when he returned he shared that this time he really didn't feel bad about not having a drink when everyone around him had several.
