So I've done some internal empirical analysis on my mean time to friendship. I have quite a bit of data now (it's all stored in the mother database called my memory, of course), so I think I can make some strong observations with confidence.
On average, it takes me one full year to develop a good friendship. Even when inebriated, I can't just call anyone my best friend...they have to be a someone. There is a lengthy process it takes for someone to dutifully peel my shell and uncover a more raw and loving side of me. We can spend hours trying to figure out why I'm still encased by a shell since at this point I should have escaped from its confines. But that is a post for another time.
In any case, since the friendship acquisition time is so long, the reward of my friendships is that much better. I've come to feel truly lucky in the random souls that have crossed my path and gradually became intertwined in my life. I try my best to hold on to that attachment for as long as possible, just so I can bask in the comfort of a radiant personality.
So when it comes time for that friendship to slowly unravel, whether it is due to a move or difference in passions, I'm left with a slight indent. The impression of what was once a good friend takes a while to fade away. Mild Sorrow and Nostalgia have front row seats to the memories that are now on replay.
We all must lose a friend, especially at this point in our 20's. I ask myself if my mind will be ready to play those memories each time.
