This person sounds shallow, judgmental, cruel and narcissistic. Pretending to be "kind" in other aspects of her life is just a cover designed to fool people. I would not want a friend like this in my life. Her negativity is a real downer.

The original question of choosing a friend based on weight or appearance strikes me as an outrageous concept. I'm really shocked at hearing your so-called "friend" would be so discriminatory. I'm surprised you still talk to her.
