I know of pretty girls who never get dates...
Cos guys always think: Aiyah so pretty sure got BF liao... ask
another girl better...
And if you're with some who's physically attractive, especially if
everyone thinks so, you'll subconsciously keep looking for defects
in the person... You'll definitely find something, and once the
illusion of perfection is broken, the person loses his/her
attraction for you...
