LOL, Meli!

Ida, I would get so upset with Mark if he invited people over (which he is very unlikely to do) or allowed them to come without telling me -- especially if there was an expectation of providing a meal. On any given day, I don't give much thought to planning out a meal -- I'll just have some vague idea -- and, often, I only have enough for Mark and me (I'm trying to do better about not having so many leftovers). To feed others, I'd have to put more time and effort into it.

I don't think I've ever crashed anything.  I've had a few people show up at the lake when we were having a thing but, usually, someone has asked ahead of time if they could bring someone. We always have a ton of food, though, so unless everyone brought someone extra, then we're good.
