If I was ever asked what my pet peeve about exchanges is, I could answer, without hesitation: the lack of communication. Seriously, how hard is it to say "hey, I shipped your gift in one, two, three shipments"? Or to answer questions that you send them? Or to send a gift note?
I'm really frustrated atm because I've received two things, neither with a note (even though it looks like one was shipped by the gifter themselves and not through a company) and I genuinely don't know which exchange it applies to. Are they from the same person? Are they for the same exchange? Different exchanges?
I'm sure I'm coming off as really rude here, but I've always been mystified by gifters who don't communicate or do it in the sparsest of fashions.
