How did you treat the girl (boy)who pursue you that you don't like!

   This days i have talked with my friend ,how to refuse the girl or the boy date.They all very bother about this things.And refuse is a art .A friend said that there was a girl pursue him ,and he said he have many friends and must be get married .But the girl didn't care about.She was cared about only she can love with he!So lovely girl ,but he was very worry about .

  Refuse is a art subject.Firstly you don't want hurt the person that he /she love you .Second we also wouldn't want hurt myself.This a difficult things.But this is an

important thing that everybody can meet this.

Could you tell us which kind of language do you treat the girl/boy that you don't like?
