Oh yeah, it's a great metaphor hat's really taken off with disabled people. I really love how in the original story, the choice of spoons was convenient, and are just a placeholder for "arbitrary units"; the slight absurdity of spoons in this context means that when someone says "I'm running low on spoons", it causes me to reflect on the entirely subjective and relative experience of ability and disability.

Edit: That is to say that whilst the person you're replying to struggles to go to Costco when they're low spoons, for a different person, going shopping may be something they find easier to do with low spoons.

Thank you for taking the time to read it! The metaphor gives us a simple way to convey a big, difficult concept.

My partner and I both deal with chronic physical issues and mental issues. A common question is, “How many spoons do you have for dinner?” And it opens the door to discuss things like I might have (physical) spoons to cook, but I don’t have (mental/social) spoons to go out to get something. It still feels like a chore to figure out dinner, but it’s at least easier to talk about. (Oh, and meal prepping or cooking a large meal for a week will typically use up all my spoons for a day and sometimes more, so as nice as it would be to only need to think about it once, I just don’t have the physical capacity to do that kind of prep.)
