I’ve been to an alcohol free wedding and it was fine, but then I grew up in a family who rarely drank alcohol. Some people are very reliant on it to have a good time, which is sad, in my opinion.
Every year at school, we had a ceilidh at Christmas where people seemed to have a great time. Then I progressed to university and every year, at the annual ball, there were people crying in the toilets, either because they were drunk, or because someone who’d been drinking had treated them badly.
Parties where there was lots of alcohol often ended with people so drunk they were ill. Parties with plenty of food and things to do always seemed more enjoyable and ended with less drama.
I guess it takes more effort to have a fun party where there’s no alcohol, but alcohol ruins many an occasion, especially for those with relatives who have an abusive relationship with alcohol. I guess, other than a hangover, those who abuse others when drunk don’t remember or care.
Unfortunately, it’s so much a part of the culture in the UK, including getting drunk, rather than just moderate drinking with food, that it’s not likely to change.
