Stupid Questions

Why do people always ask stupid questions. Is it a way to start a conversation or are they just stupid.

Examples:

I’m standing there with a Coke Cola in my hand
They ask, are you having a coke?

I have all my bags and keys in my hand.
They ask, Are you leaving?

I’m reading a book.
They ask, Are you reading?

You get the point, but WTF? Why?

I try my best NOT to do this to other people unless I’m just aggravating them.   When someone does that I instantly what to give back a smartass answer. Like I’m eating a piece of pecan pie. They ask, are you eating pie? My response is, “does it look like I’m eating a pile of shit? Do you fucking know what pie looks like? What do you really think I’m eating? But I’m too polite and answer, “Oh yes, and it’s very good”, or some bullshit like that.

I think people just constantly ask stupid questions so now it has become an accepted practice. Who know just don’t ask me. LOL
