So my neighbour and I get on well although aren't big friends as don't have a lot in common. But we're there for each other when needed. She started with the Christmas and birthday gifts about two years ago. Nothing expensive, just a token gift like a small plant or pair of socks. I volunteer in a charity shop so for her last birthday a few weeks ago I got her present from there. It was something for her kitchen and brand new costing me £5. For my birthday she gave me a bottle of red wine (I only like white) but the issue was that it had been opened and was about three quarters full. I remember her telling me that she and her son opened a bottle of wine at Christmas and just had a small glass each as they aren't drinkers. My first thought is that the opened wine she's given me is that same bottle. My son said just tip it down the sink and say nothing. But I'm feeling insulted. The wine smelt like vinegar and maybe I could have been ill if I'd drunk it. I'm so tempted to say something to her but at the same time don't want to fall out. Is my son right? Should I just write it off (she's not that bright and probably doesn't realise that red wine goes off). Aibu to feel insulted?
