I feel like crap all the time, and I’m running out of curt answers.
I don’t want to lie and say I’m good just because that’s what’s expected of me, but I don’t want to invite discussion into why I feel poorly.
My go-to response is “Living the dream,” because if this life is a dream I hope to wake up soon. Plus not only is it considered an acceptable answer, it can be played off as a joke.
If anyone needs extra context, being asked “how are you” is an extended part of the greeting here. The asker is really just saying hello still, and although some kind of answer is expected, they aren’t actually curious about your welfare. A genuine response throws people off balance, and is probably unwarranted. Think of coworkers, service workers, or even total strangers being asked this dozens of times a day.
Really though, it depends entirely on the person. With my partner I will try to give the most complete answer I can, with friends and coworkers it depends on how close our relationship is. With strangers it may be a completely perfunctory answer to a completely perfunctory question, especially if I’m not up for defending a non-perfunctory answer, but I like to keep my answers real when I have the spoons for it.
