When is the ba- baaaaaby due?

Today for the first time someone I don't really know looked at me and said, "Are you having a baby?". It's a funny thing to kind of watch people go through it in their mind - should I ask or shouldn't I. People that I see at meetings and networking events - I try to tell them when it's appropriate as to not leave them guessing too long. There is a comedian that will listen to (Brian Reagan) that has a joke about this whole situation where he says to a woman, " When is the ba-baaaaaby due?" and she says, "what baby?" and he responds, "The baby panda's down at the zoo - I heard they were due soon and I thought we could talk about it!" He goes on to point out that you don't guess at that ever, ever, ever, ever, ever, ever, EVER! Maybe a nice glowing neon sine above my head would alleviate the stress for others. It would say "Yes I am, August 4th, we find out in 2 weeks - HANDS OFF MY BELLY!"
