Tie knocked to the side

If you are a man and you want to find out how a woman treats you, put on a pressed suit and tie, but slightly knock the tie on the side, and put a powder on your shoulder. Any woman who finds you attractive, will not resist the temptation to straighten your tie and shake the fluff from his shoulder.
A tie, slightly biased to the side, gives the opportunity to the woman concerned to correct it.
