That's really funny because I actually lost a close friend of mine last spring because of that very same problem.
He started a new job where all his co-workers would do is smoke weed and go to clubs so naturally, he started doing the same. I personally, no offense, find that boring, I don't like paying money to go to a place with my friends when I can talk and drink with them at someone's house for free. Plus I'm shy so it doesn't work in my favor. It also doesn't help as they do it ALL the time, It's not fun that way.
One day he ditched me because we were sitting in a parking lot talking and he was like "aw man this is boring". He really wasn't content with anythng at all and wound up calling me and the rest of our friends boring and we haven't talked much since.
Honestly for me, as long as I'm with a great group of friends having a great conversation, then that's all I really need. I don't need to be in a club or bar or smoke weed excessivley. It's not a social issue, it just isn't something that suits my preference.
