When I was 16 and just coming up to my GCSE exams - or actually more or less in the middle of them - I remember being in the living room of our house - my dad was there too - it was in the daytime - weekday I think - and not a celebration of any kind - and my mum was absolutely hammered in a way that's embarrassing to everyone else if there's no obvious drinking context and everyone else is still sober. My dad was there and said upon witnessing this embarrassing behaviour - when you've got a good job like your mother, you're allowed to behave like that. Just for context my mum did have a high status senior management position.
AIBU to think my mum's behaviour was totally unacceptable when there's a child of 16 in the house and my Dad was totally unreasonable for enabling/trying to condone it?
