Judge Judy doesn't have a Dis user name so I'm letting her borrow mine to post her "opinion."
The hosts of the party served alcohol at the party or at minimum allowed alcohol to be served at the party. When people drink they get silly. Besides the silliness that would already be going on because it is a party, the alcohol adds to it and decreases judgement. The hosts knew alcohol was being consumed inside their home so therefore they bear some responsibility for any damage sustained on their property.
Responsibility should be split 50/50 - since each side shares equal responsibility. RadioNate's husband was drinking and goofing around, and the hosts of the party allowed alcohol to be consumed at the party inside their home.
If RadioNate's Dh suffered any damages that he needed to seek medical care for, he should pay his own bills. The hosts of the party should pay to have the XBox fixed or buy a new one. Each would be taking 50/50 responsibility by taking care of their own expenses (even if the expenses aren't equal). That's what happens when you act irresponsibly - someone gets the short end of the stick.
If RadioNate's Dh didn't have any medical expenses, he and the party hosts should split
repair costs on the XBox 50/50.
Now, get out of here and don't pee on my leg and tell me it's raining!
