Context - I had a bumped into a soon-to-be former colleague (superior) outside the office. I am about to leave next month, they only ever come in about once every 6 weeks for meetings.
He was about to leave, I was on my way in.
We only spoke for a minute or so about the meeting, then he said, ‘Well I’ll see you soon’ (he knows I’m leaving). I replied, without thinking, ‘oh you won’t see me soon I’m leaving….’ I was smiling when I said it though, not a snappy tone of voice or anything. Is that rude though?
