I had this happen to me recently, which surprised me: a colleague I like very much who knows I go to church swore in front of me, then covered her mouth and said “I forgot you don’t like swearing”. I had never said such a thing, and she added that she thought I don’t like it because I go to church, and I don’t think she was joking.
I swiftly put her right, explained that I don’t think many of us who go to church are any holier than anyone else; but I was wondering if this is a popular belief. Has anyone else had this?
