UGH! Some people just like to get a rise out of others, and don't think before they speak.
I remember my OH's brother saying to me during the pregnancy of my first "You will never lose the weight after." If anything, it ticked me off but then I decided to show him! And I did through two pregnancies! Lost all the weight in a short period of time.
Of course, this was coming from a guy who never himself had kids or been with a woman who was pregnant.
People!!
