As if they know....

So today while being at work, which i work at a library. One of my co-workers is helping this one patron out and while helping them out i was standing and doing something on the computer, while I over hear the patron ask my co-worker that was helping them the question, "How tall is she?" Now really you are going to ask them about how tall i am? As if the whole world knows it except them. I am starting to feel bad for my co-workers because not only am i being asked that question non stop, people are now asking my co-workers how tall i am. Really? LOL my co-workers even though they are all short have to hear the same question I been asked my whole life. They are probably annoyed with it now, since this was not the first time they been asked that and not last. I mean I am proud to be tall but those questions annoy me and why do people even want to know my height? They writing a book about me or something? Its a personal question, so I don't understand how can they have the guts to ask that. They wouldn't come up to a fat person and ask them how much they weigh, so why ask a tall person how tall they are? And what really bugs me is when they ask me the question and I answear them "I dont know", and they tell me I shouldnt be ashamed of my height. I am not I am just annoyed with having that question being asked over and over again. They would feel the same way if they were asked that on a daily basis. And would say anything just to have people get off them and stop asking that question. People really amaze me on how they will do anything to find information they really want to know, even though knowing that information will not really help them in any sort of way.
