Some people don't get it!

So I just finished having a conversation with my size 2 sister-in-law about weightloss. Some people just don't get it. She told me tonight that she could lose 8 lbs before dropping below her healthy weight range. HELLO? I can lose 100 lbs and just barely be reaching the high end of my healthy weight range. I wish I could be so oblivious about how food and weight affect people. (sigh) I wish this wasn't a struggle in my life, but it is. So now I need to buck up and deal with it.
