Yes, I'm sure there's only ONE baby!!!

Why do people feel the need to ask?? I get the "when are you due?" And I don't mind answering... But when it's followed by "oh my goodness!.. Are you sure?!" Umm. Pretty sure seen as how I have 5 weeks to go.... Also after getting the "are you expecting a boy or girl?" I politely respond "a baby boy" the. You have those people without filters "ARE THEY SURE THERES ONLY ONE?!?!" Ummmm yea, again, only 5 weeks left... Pretty sure they know if there would be more then one baby.. End rant.
