Like I think I am fat and could lose weight. She says I always wear the same style clothes. I say I wear the same style of clothes because they are loose and cooling, I can't wear old styles because I've grown now and they are not flattering for my body, she disagrees and says I am not fat.
She doesn't think you're fat, or she's being polite x
she's trying to make you feel better about yourself
Well, what you consider 'fat' might be different from what she views as 'fat'. People sometimes have different standards on what they view and consider as 'fat'. She probably doesn't think you're fat or she's being polite.
