Some evenings the best plan is no plan, and nobody needs to approve it.

An evening with nothing in it keeps getting treated as a gap waiting to be filled, and sometimes it is the point. No plan means no leaving the house at the time you least want to, no pretending to enjoy something, no recovery needed afterwards. It also does not require clearance from a group chat. You are the only person whose approval that evening needs.

Leave one evening this week genuinely open, and resist booking it on Thursday afternoon when the invitations land. If somebody asks, you have something on, which is true. Then do whatever you feel like at seven.
