On the flip side..the questions you ask are bypassing the obvious assuming the person you are asking is going to also. For instance, a dentist once told me my son should get braces. My son's teeth were barely crooked and didn't look bad to me so I asked the dentist if it would make any difference to the health of my son's teeth if he didn't get braces. I got this stupid 5 minute diatribe about simple oral care, flossing, etc., the kind of care my son did on a daily basis anyway. The dentist didn't take into account that my son had been coming in there since he was 3 for his biannual cleanings and that he had never had a cavity. Well....DUH! I'm forced to say "I understand that, my question was...", or I have to phrase the question starting out with the whole rigmarole ending with the actual question I wanted to ask.
I get this all the time, and from smart people too?
When people ask me questions like that I can assume they know existing simple facts that most people know before giving them an answer.
Are some people too literal?
One time I was at a stingray encounter at Grand Cayman. It turned out that those things freaked me out and I couldn't get back to boat fast enough. The same thing happened with one of my friends in another group. Later, when all of the friends were together at dinner the two of us were laughing about it when one people (a scuba diver) in the group made this comment, "next time just remember that if everyone else is having fun doing it then you should realize there is nothing to be afraid of". My friend and I looked at each other then said WHAT????
