These have been messing with me lately and I have no idea why. I'll write "anybody" in a sentence, move on, revise later, change it to "anyone," move on, come back later, change it back to "anybody," etcetera etcetera.... Ditto with someone vs. somebody. It's becoming a thing with me. Almost like a nervous tic, and it seems kind of stupid because I don't have any strong opinions, positive or negative, about which one to use when. Yet I keep messing with it like it's vitally important, which I doubt it is. Thoughts? Preferences?
