And when it gets pointed out to them, they blow a gasket. I know one overweight mom who pitched a fit when her kid brought home a letter from school indicating the kids BMI (taken as part of a state health screening) was high.  They didn't judge, the letter merely said they should follow up with their pediatrician. She posted a big rant on FB saying her kid wasn't fat and was 'very active'. Honestly, the kid is overweight, just like the mom.
