What the Pregnant!!!

Well it is finally obvious to the world that my belly isnt fat and that there is actually a baby inside. I think the child grew overnight because suddenly I look pregnant all the time instead of just sometimes. It is so fun. I love looking down and seeing this little thing growing inside of me. I am actually needing to break down and get myself going with maternity clothes. Now that I am actually showing, and it is pretty obvious that I am pregnant, I have noticed that people are particularly kind and friendly to me. I have a few examples.
EX 1: I was at Old Navy buying some clothes and a lady I have never seen just walked up to me and said "ohhh!! Congratulations!" She then proceeded to tell me her whole life story and then told me that she never knew pregnant women could look cute in a white shirt. It was so strange.
EX 2: At work, usually people want to hurry and get through the check out process and go on their merry way. These past few days that I have been looking pregnant, more people than ever before have talked to me about my due date, the gender, their kids and pregnancys, doctors, child birth, you name it.
EX 3: I was shopping with my sister and feeling really poopy. Where she was trying on jeans, in the dressing room was a long and soft bench. I asked a girl if I could just lay down on the bench. She said yes. A few minutes later, a guy came over and told me that only 1 person was allowed in the fitting room at a time. He then noticed that I was pregnant and laying their all sick on the bench and he said "Oh my gosh are you feeling okay? If there is anything we can do, let us know!" Then when we were leaving he just kept telling me how exciting it was that I was having a baby and how he wanted me to feel better.
These are just a few of my experiences, but there have been many other similar experiences just in the last few days. Oh and the best part was at church, every woman there wanted to look at my tummy and touch it and talk about it.
Why are people drawn to pregnant women?
