I'm just curious..

Random question, but anyone know why random people or people who aren't close to you are so eager to know the sex of your baby or when you're due? I keep having people ask me and even this one person asks me everyday if I know the sex yet......is it weird that they are so nosey? Or are they just intrigued? Not even being mean but it Makes me uncomfortable to be honest...Does this make anyone else uncomfortable? Maybe I'm just paranoid...
