Yesterday I spent time with a friend, which felt like college, although college was many years ago for me. It felt like college because our getting together was spontaneous, she was finishing up some work, I was drinking coffee. Later we went for a stroll, going nowhere in particular, talking about whatever came to mind, staying up later than either of us intended. Then we happily went our separate ways with no drama.
To me the ideal companionship is just enough "it's us against the world", with enough, "actually I like the world for the most part" to make plotting for social revolution an unlikely outcome.* It's conversation with enough depth to face the eternal question of "I wonder where I fit in this particular universe" knowing that one's compatriot wishes one well as she too ponders her place in her current life, perhaps the life she never expected. This sort of time together gives me courage and energy to face whatever comes next.
I highly recommend it as a way of coping with chronic illness or just being alive. Oddly enough it can be hard to come by.
*In general I have nothing against social revolutions, I just don't find them helpful in dealing with chronic illness (at least not for me!)
