Asked out by someone from past, nothing really happened though as one of us had to move away. Anyway I told him I'd be in his neck of the woods Wednesday (meaning tomorrow) after he asked; he took this to mean next week, and said he was starting work then and felt his social life was about to disappear (complete with anxious emoji). Asked me a question blah blah. Do I reply? I'm happy to see him as a one-off with no expectations. I'm not that bothered either. But is it desperate/weird to be like oh I meant tomorrow not next week?
