DD(18) is bestfriends with a boy that is autistic, they get on well and he seems to listen to DD and his mum has said in the past DD seems to just get him.
This evening he went to a party with another friend, DD didn't go as only people who attended his secondary school were invited and DD didn't. The friend has just messaged DD saying he was fighting with someone, she doesn't know why as she wasn't with him at the time and he was refusing to leave. DD messaged him and he agreed to but is asking if he can sleep here and not at the other friends as he's slept here a few times so he's used to it where as he's never slept at the friends house.
WIBU to say no? Apparently his parents are away so he's staying with another family member who won't be happy if he goes home drunk
