Genuinely curious. My husband and I don't see eye to eye on this. I think if I'm cooking (it's almost always while I'm cooking) and I fancy a glass of wine, and no other adults are in the room, I should just pour myself one and drink it. DH thinks this is the height of bad manners, and to be truly civilised one must hunt down every other adult in the house, inquire whether they too would like a glass of wine, and fetch them one if so.
I think this is ridiculous, and if it were enshrined in law I would rather forego the wine than have to traipse around asking other people if they too want a glass and then delivering it. Of course if someone was in the room with me I would absolutely offer them a glass.
If it matters, neither of us are big drinkers. The bottle in question tonight had been half empty for over a week, so it's not like we both share an evening glass at the same time every night and I was breaking some tradition (in contrast to coffee -- we always take turns bringing each other a morning cup). He just thinks it's plain weird and bad manners that I'll pour a glass without offering him one.
YABU: Not offering wine? Absolutely vulgar.
YANBU: Wtf is this weird idea
