I don't drink because I don't think it should be necessary to drink to have a life. I think too many people drink, and that isolates those who don't. I think drinking is way, way too integrated into the society I know. I don't think anything that unnecessary should be that integrated. I am expected to drink. People would take it for granted that I do, based on my age and me being a student.
When I tell people [who do drink that] I don't drink, they don't understand. They look at me funnily, and from that moment on I will surely never be able to talk with them like a friend - because I'm not like them, I'm strange and eccentric. They don't have anything in common with me, and I cannot lead any discussion with them because I can't relate to the frequent mentions of alcohol, which is one of their great interests, so much it's a part of their life, a basis for their lifestyle.
Thus, I cannot have any similar lifestyle; I cannot be a social person, I cannot get a lot of friends. Not because such a lifestyle is something I couldn't handle or something I wouldn't be interested in - but because I don't drink. Everyone with that lifestyle drinks, and if I want to do the same, then I have to drink too. If I don't, then I'm a foreigner among them, I wouldn't belong at all if I tried.
This wouldn't bother me if it was just a group of people having a tendency of including alcohol into their lifestyle. That's not the case, because practically -everyone- drinks. There is no room for the others, those who choose not to. There are too few sober people to be able to maintain an alternative society.
I don't drink because I want friends who don't judge people based on whether or not they drink. I've chosen not to drink and it'll stay that way. Those who cannot accept that others make choices like that, aren't worth my attention. This is much of the reason why I've chosen this. I want non-drinkers to have the same chance of being social as everyone else, because I know there are several of them and I know how they feel.
