I give away fun trips to folks who miss each other.
I’ll send college roommates who’ve moved to different cities to a lovely place for a few days.
I’ll fly someone who was a high-school foreign exchange student to visit her host family.
I’ll arrange for buddies who live on opposite sides of the same city to spend a night on the town (and treat each of their families – if they’re stuck at home – to a delivered dinner from their favorite restaurant, so they’re not too jealous).
How I pay for it.
Nothing complicated. I do ok at my job. This is where I spend my disposable income.
