Question

Why are you bothered, when someone asks you "How are you?"?

Answer 1

You're just a little grumpy

Answer 2

No one should be. Of course, if you're someone who looks like you don't really care you just want me to talk to you so you can sell me something, I might ignore you.

Answer 3

That doesn't bother me, I think it's common courtesy.

Even if they say it just because they can't think of anything else to say.

What's stupid is when people introduce themselves and it goes:

Person 1 to Person 2: How do you do?

Person 2 responding to Person 1: How do you do?

They don't even answer the question.

I find that weird!
