surely it is reasonable to know roughly where the people who live with you are and what time you can expect them back?
Yes. However, as facts, not the starting point of an argument.
So I say to my 20-ish children, when they are staying in my house, "what sort of time will you be back? where are you going? who are you going with?" and they tell me, just as we would tell each other if we were going out other than as a couple. That tells me not to be surprised if there's a taxi pulling up at 2am, or who to phone if it's noon the following day and they're not back.
What I don't do is then embark on a "whatever do you want to do that for, he's a wrong 'un, I wouldn't go there if I were you, haven't you got an essay to complete?" because, you know, they're an adult.
And because I'm never done that shit, the "what time will you be back, where are you going?" never results in an argument, because it's not meant to be an argument.
