If the girl is alone all her life is that happiness? Society pressurises a woman to get married and I have seen it everywhere that if u are fat and not married society shuns you then what kind of happiness are you getting?
You are comparing two different things. The poster assumes that if a person is fat he/she can not be happy. Which ofcourse is far from truth.
You are talking about the desi mentality of treating women as "bhair bakriyaan". Buyers check to make sure they are getting their money's worth. Its a stupid evil coustom and unfortunatily girls do get trapped into this cycle. Education( and I don't mean degrees) is the only hope but I feel sad when an educated girl like you feel that you are worth more after losing weight.
