Well, funny you should ask this question!
Trouble is, I don't do that and only surround myself with those who I like and like me. The trouble I am finding is that even in my 30's I come across people in my workplace that no-one likes and is a horrible gossip, but those around her keep on her good side. They all get along with her to her face and play the 'polite game' with her. As a result they all presume to be friends (even if it's for the wrong reasons). I on the other hand don't play up to all that rubbish because she's a horrible person and am a constant form of gossip for her!
I don't wish to be close to her in any shape or form and will have to learn to live with her as an enemy! Mind of matter!
