just say no la.

Apa susah?

But u guarantee will feel "left out" when u see ppl get promoted left n right. In office of course those who hang out together after work is closer and have a lot more inside jokes.

It will end up the same thing. Confidently tell ppl "No, i dont want to join" and also confidently accept the social drawback. From what i see, most of the ppl who complain like him is the one feeling offended when others are gaining advantage for doing something HE DIDNT WANT TO DO. He feel it's unfair, because the scale didnt tip according to his favor. The world revolves around him is not an understatement.
