You know those weeks then nothing really went wrong, but you still had a really miserable time? Just needed a little pick-me-up to get you through to the weekend? I'm kind of having one of those weeks.
My version of a pick-me-up: I find something mechanical at a thrift store or an estate sale for cheap, only a few dollars, that doesn't work, and I just tear it apart. No attempt to fix it; just taking it apart and enjoying the concept of how each part fits in the parts around it.
