"How are you?"
People who make that inquiry- don't expect a truthful answer, do they? They should, of course. Otherwise there's no point in asking. But no, they expect to be told that you're fine even if you're at the death's door.
"I'm fine/I'm good." is usually the canned response we hear from that question. Why? Is it because social norms influence everyone to say such an untruthful reply? I don't know. But at some point, people tend to hide their real emotions. It's just one meaningless social convention.
How am I?
I'm a donut, thank you.
