How To Be Repulsive in a Friendly Manner

If you are not compatible with someone; but, they insist on becoming friends with you, explain you are not not compatible. Tell them you do not prefer their type of personality or lifestyle. Also, tell them you are searching for someone different. Tell them may meet someone who is more compatible with them some day. That way you separate from them potentially; except for the most stubborn; and can be free from their annoyances.
