My DSD is 31 and for context doesn't work, I don't think she ever had in the 13 years I've known her. She has a flat about 20 miles from us.
She comes to us for Christmas every year and her dad asks her to bring a contribution for the day, which is usually the alcohol she drinks. I wouldn't dream of asking for money towards the meal but feel bringing something is the right and thoughtful thing to do (though she needs to be reminded every year).....
She brought vodka and seemed to have a few, mixed with coke, over Christmas Eve and Christmas Day which she made herself. However this morning when packing to go a two thirds full bottle of vodka is with her stuff to take home. So clearly she has been drinking our booze and even this tiny contribution to the day she is taking home.
Her dad says he will speak to her at some point. I know she'd make a scene, shouting and slamming doors (yes, at 31...) so today probably wasn't a good day, but am I being petty and unreasonable expecting her to leave the vodka here? I would have happily drank it!
