Inspired by an aunt and uncle of mine. Is consistent slight profanity ok with you? As in after you drop your fork or stub your toe you say dam-it, God-dam, shit, or something like that.
I'm not a fan. If it is truly a rare occurrence, then I will mention something the first time, but might not after. If we spend a lot of time together & you regularly cuss, then I will ask you not to do so around me. I tend to pick up words I hear
often & use them without thinking. I made the effort to break my cussing habit years ago & would prefer it didn't return.
Its pretty funny hearing them talk because only them and another uncle of mine talk like that its interesting.
