Mumsnet is full of people who get tipsy on a thimbleful of champagne at Christmas. They exclaim in horror about anyone having drink more often.
Honestly, my experience is the opposite. When I used to drink (as I said upthread, 5-6 glasses of wine a week on average - basically 14ish units a week) I felt that was the "norm", both due to my own friendship group and due to MN.
Having a glass of wine with dinner, maybe two on a weekend, a cocktail with friends etc is so normalised on here. And not doing that is described as "pious", ffs.
It's only when you stop drinking, and keep it up for long enough for it to stop being a habit, that you realise no - it's not normal for everyone, and actually it's a bit weird that every social occasion seems to be accompanied by booze. Even kids parties, in my circle of friends. These are people who would be horrified if someone cracked open a can of Strongbow at a kids party but, somehow, it's ok if it's Prosecco. I used to think the same. But now I've stopped and got out of that mindset, it just seems crazy.
What I've also been struck by is the friends who think it's good I'm not drinking, as then they don't "have to" either. These are confident women in their 30s - who otherwise have no problem speaking their mind - but they will admit to drinking on occasions when they don't necessarily want to, as they feel it's rude to say no. I think that says a lot about the culture around alcohol in this country, perhaps more so in more "middle-class" and older circles. Teenagers aren't drinking so much anymore, and nor are people in their 20s...so why is it so ingrained in those in their 30s and above?
