New one (maybe not): requested an item from a new-ish swapper who follows several items I have listed; I am following none of theirs. They come back with an email that I took to be very abrupt/borderline rude & demanding (per the rules, I'm intentionally being vague). While this person has something I am interested in, it's not a unicorn and something I can probably get relatively easily and wondering if I'm being sensitive or should just cancel the swap...and if so to the cancel, should I point out (politely) the reason? I've groused before about people requesting swaps from me that I've responded same-day to and they canceled them without a word, so don't want to be a hypocrite. I also really, really do not want drama.
