Lying on the hood of a car looking at stars with friends is a top-ten night that costs nothing.

The nights that stay with you are almost never the expensive ones. What makes that one work is a combination nothing can be charged for: dark, warm metal, nowhere to be, and people who are easy to be quiet around. This kind of night has no structure at all, which is why the talk gets good.

Set one up on purpose rather than waiting for it to happen. Text two people, pick somewhere with less light, go out after dark, bring nothing. If you have no car, a field, a roof, a parking lot or a set of steps all work.
