Am I overthinking this?

I hate to discard pants that are still good enough for painting. I also hate painting, so I don't need a lot of painting clothes. Still, I just can't see throwing these pants away when they've got some life in them. Also, they're clean, so there's the soap, water, and energy investment to consider. If I'm going to throw them away, I should wear them once more and throw them away dirty. That's less wasteful. They're too good to toss, too worn out to give to the thrift store. As a matter of fact, they came from the thrift store.
