DH and I don't drink. We're not evangelical or derisive of people who do. I just never started and DH used to as a teen but gave it up 17yrs ago.
DH is on a stag weekend right now and the majority of men there are completely indifferent with regards to who drinks what and why. A couple of them however, seemed to mishear DH when he said he was teetotal and presumably, what they heard is "I'm from Planet Zog and I will actually be dipping my tumescent cock in my beverage and sucking it up that way". You'd think so anyway from their ashen faces, incredulity and on two occasions, the downright refusal to buy him "a bloody coke" and then proceeding to plonk a pint in front of him instead.
They keep going on about how it's like having a maiden aunt along and last night one of them threatened to spike his drink.
Ironically, their insistence that DH needs "a good stuff drink inside them" (yeah I could psychoanalyse the shit out of that tbh) is 673% duller than DH not imbibing their alcoholic offerings in the first place.
On a slightly serious note - I know, it's AIBU and not home of the serious - DH is quite sensitive and I know it makes him feel like he doesn't belong. The groom and most of the other blokes don't care but I know DH and I know he'll come home and play the comments over in his head. And that's ridiculous. It's bullying.
Why does this still happen?
