This is a scenario I think of sometimes: you get one hour in a sealed room with a person of your choice. You can do anything you want for that time and neither of you can ever disclose what you did/spoke about to anyone else.
Who do you take and how do you spend the time? I can't quite decide - I'm guessing a lot of people might use it as a hall pass or to confront someone they've always wanted to confront, though I suppose it could get a bit tense to do the latter!
