The elephant in the room

I had a job interview yesterday and felt fairly confident going into it except for one thing...I have a giant belly that is obviously very close to popping! I thought for sure as soon as I walked in they would want to ask when the baby was due and they would realize that Maya should be here pretty close to the start date for the position.
Instead my giant stomach was like the elephant in the room....at least to me it was :-) The 3 people who were interviewing me never asked about it. They did go over the dates a couple of times (maybe to make sure I knew), but they never said anything direct. At one point I said "obviously I am expecting a baby soon" and one of the guys sarcastically said "no way!" and then proceeded to tell me that they could not ask about it. Pregnancy cannot legally effect whether or not I get the position so instead it was just avoided.
Obviously at every second of the day I feel the baby and am pretty uncomfortable at this point so to me it is something I always am thinking about...this is why it was so odd to just avoid the topic. But it is probably better they don't realize how close the dates actually are.
