Drink to have friends
Drink to not get bulied
Drink to have a social life
Drink to not commit suicide
That's working backwards.
Yeah, I deleted that post. It was, um, not entirely not nonsensical
Basically, I pretty much magically developed a social life and many more friends after I drank for the first time, and then kept them without necessarily having to drink. I found all the social stuff very difficult previously. Drinking at two particular parties relaxed me enough to be able to talk to the people there who I didn't know, and they became my friends ever after. I had friends before this, but not as many and not really in a going-out-and-doing-fun-and-wholesome-activities-together sense. I believe I've already detailed this in an earlier post, but whatever.
Conclusion, I don't think it's a good idea to drink purely so that people will be friends with you because of you drinking, which I
think is what you were decrying, but I see no issue with drinking in order to help yourself relax and make friends the usual way, if you usually have difficulty with that or even if you don't. It's been done for thousands of years and it seems to work.
tl;dr: Drinking to make friends = bad. Making friends while drunk = OK.
