DH was going out for his work's Christmas party. I asked him what time he'd be back (for safety reasons, as he tends to drink more than usual at these events). He told me that he'd do what he wanted to do and not to wait up for him. I told him well, no, you're a parent and you can't just do whatever you want if you're family is waiting for you at home? I can guarantee that the other people with children will have agreed a time to be home with their partners before leaving the house, no?
