My Dad never drank and my mum would only have an odd drink here and there. I am talking maybe 3 to 4 times a year and that would be one drink only of each occasion.
My hubby probably only has a drink because I enjoy having one. I enjoy a champagne/white wine and on a hot day, I love a cold beer. I would probably have a drink a few nights a week.
ETA Hubby doesn't drink much, so when we go out he's the designated driver!
