Last-minute invites can be flattering and stressful at the same time. The trick is a simple formula: thank them and give a light boundary, decline clearly, and offer a future plan. You do not owe a detailed explanation, and a neutral reason keeps it kind without inviting debate. People usually read a confident no with an alternative as care, not rejection.
Try, "Thanks for thinking of me. I'm keeping tonight low-key and won't make it, but I'd love to plan something next week if you're free." Or, "I can't swing something last-minute tonight, but please keep me in the loop. How does Wednesday or Sunday afternoon look?" If you want to go but need more notice, use, "This sounds fun, but I need a day's notice to make it work. Can we schedule it for this weekend?" When it is a hard pass, "I'm going to sit this one out, and I hope it's great. Let's pick a date soon for coffee or a walk." If they push, just repeat your line once and change the channel: "Can't tonight, but I'm excited to catch up next week. Tell me how it goes."
