I have a couple of bottles of champagne I got for my 21st and a bottle of wine from my birth year that my dad got when I was a baby and gave to me when I was 21 (was meant to be when I was 18 but he forgot...). I left them at my mum's when I was drinking as I didn't trust myself not to just drink them (I was saving them for a special occasion). Now I'm sober they are still there. I don't think I'd touch them but I'd rather not take the risk by having them in my house. I live alone though. It would be different if I lived with other people.
