You serious? I'm not saying saying ALL men are not pretty, but i don't think women get attracted to looks as quick as men do. We are created differently, that's the reason the shariah hasn't made it necessary for even pretty men to wear niqaab! Also a smile from one muslima to another muslim could be the start a friendship. And a drastic unhealthy one as well. Islaam has taken all measures to protect muslims from falling into any unwanted situations. Hijaab is one of them
