Why???

Rachael • I'm a 34 year old RN and mother of three (soon to be four). Kinda feel like a 1st time mom, since my youngest is 12!
Why does everyone get so angry when someone offers sympathy or empathy over the fact that we are pregnant over the summer?
I kinda appreciate that people acknowledge that this heat and pregnancy aren't a fun combination. 
I don't understand the anger over it....
