I've noticed a big difference in how people treat you when you are pregnant. Now that I don't look like a puffy overweight 30 something, but an actually pregnant woman - people treat you differently.
Twice this week someone has asked if they can touch my belly. Several people have asked to help us move next weekend "since you shouldn't be carrying stuff". Yesterday a woman at the Sports Authority told her 4 year old to "be careful with the pregnant lady in front of you". Strangers open doors for you, men and women smile at you and at work they now let me decide where we should go have lunch.
I gotta say, 2nd trimester pregnancy is filled with sweet unexpected happenings, kind of like a great surprise upgrade at an expensive hotel.
