That's certainly one category of friendships. You just have to be aware of what category of friends reach person is, and try to engage in ways that are consistent with the frame of mind. There are friends I'm intellectually inspired by, like you say, friends that I do activity X with, and friends who I've had my entire life with whom I can completely let my guard down with. The third category is honestly the most special one, since It's really really hard to recreate it in adulthood.
