Hm… Normally I would ask you to point out the parts that were offensive to you - but I already know you wouldn’t respond.
Here’s something else you can report on, that might actually have a chance of getting removed:
Dear co390,
My time and effort spend with you were clearly wasted. I can see that now and feel sorry and foolish for trying against my better judgement.
I also suggest that you show this thread to your parents for emotional gratification.
Goodnight.
