I totally disagree with this, since after all, women get approached all day, every day. They get told how beautiful they are a hundred times a day. She also notices that all eyes are on her all the time. If a woman gets rejected, she's got a line of prospects right behind him.
We're lucky if women stay single for even a week against their own will, not to mention how easy it is for them to blow us off for an already planned date, either by giving some lame excuse or ignoring us altogether.
