My own kid only a year or two ago thought that being drunk absolved you of all responsibility, and that saying and doing horrible things under the influence somehow didn't really count.
My dd is 11 and this is something that we've been discussing more than I'd thought I'd have to.
Dd knows alcohol does not excuse bad behaviour, being drunk isn't a free pass to do whatever you want to who ever you want.
But at the same time she's told to make allowance after allowance for her gran, who is an alcoholic, and I will hold my hand up to doing this myself, when dd says her gran upsets her by not coming to see her, she's told " she doesn't mean to upset you, she's drunk", when she's says horrible things, dd is told "she's drunk, she doesn't mean it"
This is the adults in her life telling her this, adults making allowances for another adult, the same adults would watch the news and say being drunk doesn't excuse for hurting people, but at the same time will say to dd, "ignore your gran saying/doing she didn't mean to hurt you, she was drunk"
She got help for a while and made no attempt to speak to dd about the things she had done, she's never said "sorry, I shouldn't have done x, y or z" and there was this general feeling of "she's getting better, don't upset her" but dd has never built up the trust again and built her guard up around mil. Family are genuinely puzzled why dd feels awkward around her gran, but she's getting the message from the adults in her family that one of them will cross her boundaries, but that she can't be upset because that person is drunk and didn't mean it. And as mil is drinking again, everyone is back to making the same excuses.
I know I've gone off track a bit, but found the making allowances for drunk people interesting. I guess I'm guilty of looking at the whole world and saying being drunk isn't an excuse for anything, while when mil first started drinking, I made excuse after excuse for her behaviour precisely because she was drunk, because I didn't want this woman who I love very much to be the one responsible for causing so much pain, it was really difficult to accept that someone I love and used to trust with everything is capable of shitty things, of hurting people, blaming alcohol made the family hurt less, if that makes sense?
I love my mil, I'm sad for her, I'm sad for what she has lost, I'm sad for what she stands to lose, I'm sad for the people who she has hurt, but I won't tell my dd to make allowances for her anymore, mil is someone who has and still does behave shittily.
