How to refuse

  How to refuse a person whom one has first in the beginning looked at to see if such person would be right for oneself:
Be friendly, praise the other person's good qualities and tell that you yourself are looking for a different type of person, people more suited to your taste. "Better luck next time... I wish you good life and luck in your search. Unfortunately did not succeed this time. One cannot build upon such which one knows will fail, be unsuited to oneself. Better to save time and one's sense of self-worth and invest on those with whom one gets well along and whom one feels to be suited to oneself. Goodbye..." (factually said, not overly nicely)
