Ds is not very trustworthy, he's very absent minded leaves taps running and goes off to work, forgets to turn off lights, leaves doors unlocked etc.
He has ADHD.
He's 23 now and last year we trusted him while we had a long weekend away as a sort of first time to see how it would go but when we returned he'd had people in which we specifically made clear he was not to do while we weren't there but he ignored this and had people stay over, he denied this at first until we found empty drinks and other evidence so he admitted he'd had people to stay, the place was an absolute tip.
We've booked a holiday this year and it's causing so much anxiety, he can't get the time off work now to come with us as was the original plan and we can't relax with him home alone.
Would it be unreasonable to ask him to stay elsewhere while we're away so we can lock the house up and relax?
We don't have family near by and he has work but I was thinking a local friend or a cheap b&b or something.
Otherwise I think we'll have to cancel.
