What I was hoping for were ideas that let you see folks in many situations, especially those that might show you more about their character and behavior than you would be likely to see at, say, a restaurant or a theater.
There's nothing more "everyday" and revealing than seeing where a person lives. What's on their walls, what's in their fridge, etc. Endless conversation points too. Generally the third date or so is when you might see their home.
And, if they won't let you see their place, it's a bad sign.
