Well I guess it is because we all just want to hear input on stuff from other people. Even if we know the answer. We just wanna hear what other people have to say :) I think theres nothing wrong with that
Its because those people have no common sense! Like today I was in the kitchen opening a yogurt container, and my mother-in-law who is in the kitchen with me and can see me clear as water asks me what I am doing. :/ I just felt like saying, "Walking my dog!" But I respect people who are older. Lol I understand a little kid asking obvious questions but grown adult? Lack of common sense.
maybe they just have an open mind & are looking for other opinions ?
This IS a trick question isn't it? You are asking a question you already know the answer to. The answer is so obvious.
They ask cuz they're bored and they want to interact with others. They also aren't usually looking for a serious answer. They are trying to bring out the humor in people.
to check another capacity
That is exactly the example of the kinds of questions that I am referring to...and then they look at you as if you owe them a response.
