Coalie, truly, there is nothing negative here rather than what you put in. There is nothing in this author's note that says they wrote it for themselves RATHER than their recip. There is nothing negative about saying briefly "written for X prompt". What if the recip had multiple prompts even? Is it negative to say which one was written for?

It's like you're writhing in agony over the possibility of this author being perceived as anything other than a gift-delivering machine.

This is someone’s gift, it seems presumptuous and a but rude to gift them something that long (and I love longfic) and also give them a bunch of research notes too.

Rude?????????
