Terminology

I've always thought of the weekend as Saturday and Sunday. There's the weekend, weekdays, weeknights, and Friday night—four separate blocks of time. I don't necessarily prefer the definition of "weekend" that doesn't include Friday night; it probably makes more sense to include Friday night than not to. My parents just never really included Friday in the weekend, so I didn't either. What drives me nuts is that there's no standard. When someone says weekend they could mean either Saturday and Sunday, or Friday night, Saturday, and Sunday. Some people infuriatingly switch between the two as it suits them. Sadly, I'm one of those people. But it's annoying. "Weekend" should have a concrete meaning.
