This is one of the worst things. The guy I play guitar with is usually 15 min-2 hours late, so, like, yeah, I am really bad at just sitting in my house waiting for him to show up and shit. Then he gets there and I am worn out from waiting.
Sounds like my in-laws. Ho!
Speaking of in-laws, what do you call two people who are vaguely related, but by two degrees of marital separation? So, like, my husband's sister's husband is my brother-in-law, and my brother's sister is my sister-in-law, but what are they to each other? Or what about my husband's brother's wife's brother, AKA my brother-in-law's brother-in-law? This is a Thing that Comes Up, because some of the extended extended family lives locally and often shows up at some point on Thanksgiving.
For a more commonplace example, what about the relationship between my parents and Pedro's parents? They share the same grandchildren, but there is no word for the familial relationship there. Not in English, anyway -- my FIL has told me the word they use for it in Argentina but I cannot for the life of me remember it right now.
Anyway, all these people who are incidentally-related-but-not-really...I call them "outlaws." But it doesn't seem to have caught on.
