followed with ‘I wasn’t aware is so important to you. I didn’t want to insult you and if you felt so, I apologize. The word fuck is one I use very often, but I’ll try to control myself around you’
Note I didn’t insult the coworker (no fuck you or fuck off), but simply said ‘fuck’ out loud due to a job error.
I remember working in the London UK office and we curse non-stop over there it’s great. Whenever our colleagues from SF would visit they would always be surprised how much we swear. I’d see them do the turnaround like, ‘what just happened?’.
