Nobody says it anymore

I've heard it explained that "hey" used to be more of an urgent way to get someone's attention, rather than a casual "hello" like it is now, so it sounded rude to some older folks.
To me, 'No problem' is just short for something like "oh don't worry about it; it was really no problem at all and I'm happy to help".
Colloquialisms are fun like that.
The context in which the listener is expected to comprehend communication is important if the speaker hopes for the intended message to actually be communicated.
If the speaker chooses to ignore how the listener is expected to perceive their communication then I'd say that actual communication was never truly their intent... seems more like linguistic masturbation to me.
Bullshit.
If you infer something from something that's on you.
I feel that kind of interpretation is more region specific. Specifically, West Coast?
Midwest, actually!
