I notice that I like to write dark things…

Me too but I’ve come to accept that we writers are a broken lot. That being said I thought your note was coldly polite, which is odd considering the word choice.

I agree with Mr. Quick. This note was “coldy polite.” I think that is the best way to say it.

I wrote it for that effect

I never doubted you. To clarify, I meant that the words themselves were warm but somehow despite that, the note comes off as coldly polite. I admired the dichotomy.

Oh i was agreeing with you :) I was glad you caught that

“Nice to have known you " perhaps a better “adieu” as the tense follows the note.
“Looking down upon you” ?
Otherwise the emotion of standing apart and looking at what is happening works well.
