I don't drink, never have (except as a teen). It's not for any other reason than I don't like the taste or the effect it has on me. No big deal.
My friends and family are aware that I don't drink yet one of them insists on buying me alcohol for every occasion. It's my birthday today and I received a bottle of prosecco?! WHY???
You wouldn't offer a non-smoker a cigarette or cook a vegetarian a steak dinner so why is this any different?
