There’s an old riff that if you want to make a friend, ask them for a favor. It’s counter-intuitive advice. Wouldn’t you want to offer a favor to cement a budding bond? That might help too, but if your potential compatriot is willing to invest in you and your shared connection, it will quickly deepen the affinity.
isn't it amazing? i know it's so cliche, but you really do learn a ton about yourself, and about relationships.
