Tips for the start of uni (Freshers and onwards)

[Isphera]

I don't see why the non-drinking thing is a big deal - so I decide that my beverage of choice for the evening will be an Orange Juice or an alternative, why does that affect the evening in any way? I'm still hanging around with people socially, I'm still drinking something, it just doesn't have any alcohol in it. Or am I missing some obligation of society that instructs everyone to drink and force all the teetotalers to the abyss.

Although, if I said the above out loud word-for-word, I'd expect to be punched. Hard.
