I want to go back to a prior conversation because I received a comment like post
>>6859 today and I feel I can better articulate my feelings while it's fresh.
The comment was basically "Thank you for writing x/x I loved it! Can you write more x/x?" It was on a fic I was proud of and am happy to hear someone liked it since I often write into the void. However, when I write a pairing I tend not to return to them, there will not be another story for this ship from me. As such it's hard to reply, I try not to leave impersonal one-word replies like "Thanks" but I don't want to tell the person "Thank you, but I don't have any more planned," since that sounds dismissive and rude.
In the past when receiving requests to continue oneshots I've replied with "Thanks, maybe in the future." but that's just a lie. I don't know, there's definitely some self-consciousness over disappointing strangers on the internet.
