As of this moment, i dont have that kind of friend but later, when i would have, i will juts let that person but i won't support his/her deeds.. How about you?
I believe I am very fortunate that as of now, I dont have a friend/companion who's like that. But I used to have a classmate who's a social climber and she's just overly irritating - maybe, I really wont get along with such sort of people.
