It's so easy for guys to say that, but you don't know what its like for a girl. Height is something we don't have control over.
I have a friend who is trying to get married, but everyday she keeps getting rejected, and its based only on her height. Shes educated, beautiful and caring, but even before seeing her, the guys family just reject her because shes 5'2.
Just imagine that. You spend over half of your life in education, just to make sure that you can find someone decent to marry, you don't have anything wrong with you and you haven't put a toe out of line, but you're just rejected on the basis of your height.
Not only is it saddening for her, but it's even worse for me, who has to see her cry, over and over again. It's a pity that people are like that, but inshallah she'll find someone decent to marry.
