Alright, so, I'm 21 years old. I've been working at my job for almost a year now. I've been nice and friendly towards everyone. And for the most part people at work seem to like me. I've gotten invited to go to "parties" where, the next day I find out all it was was my coworkers getting drunk, dancing like idiots, and sitting in front of the television and giggling cause they're drunk. I've gotten invited to go clubbing or to a bar. I've never been much of a drinker. It's not like I can't drink- I just don't feel the need for it. The same thing goes for drugs as well as clubbing. I've been in a relationship with my fiancee for 5 years now. I've got a disability in my arms so I don't feel like messing up my health any more with drugs. I also don't see the need for them. I don't go clubbing because my coworkers always tell me it's for them to have fun and meet guys. I don't go to bars because they all just want to drink. I feel left out cause I'm friends with coworkers at work but I don't hang out with them cause none of them seem to have the same interests as me. I like to play games, travel, watch movies/shows, and just have fun. But, all my co-workers feel that makes me childish and immature in comparison to them and so they don't talk to me much outside of work related topics. Is it normal that I enjoy my hobbies, don't drink or do drugs and so I don't hang out with my co-workers?
