Sorry long title, couldn't think how to word it.
But if you were going out somewhere, would you generally tell your partner/spouse exactly what time you'd be back, a more general "I'll be a few hours" or nothing at all?
We have young children and I'm pressuring that changes things slightly, also if other plans/commitments would require an exact time I get that's different. But in general on a day to day, going to the shops or a few drinks, what would you do?
