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.
Why would you need to apologize at all? You swore. It’s not a big fucking deal.
Right? How about this: I’ll keep the swearing to a minimum if you remove all the religious bobbles from your desk and stop talking about God. You don’t have a monopoly on being offended, and respect goes both ways.
If you have a burning desire to say anything then “Thank you for letting me know how you feel.”
