Same. "I don't _want_ to, but I'd love to join you anyway" is my way. My wife and I both answer with some variation of this now and the extra info is helpful.

Same. "I don't _want_ to, but I'd love to join you anyway" is my way. My wife and I both answer with some variation of this now and the extra info is helpful. Sometimes the rest of the conversation goes something like: "Fair enough, let's go for a couple hours and if you're still not into it we can make our way out." OR "Oh, alright, I didn't really want to either, so let's just [send a gift | invite them for dinner next week | whatever]". As for chores - well, they have to get done, but the protest can still be made and noted so it's not a surprise when something is done half-assed.
