I totally understand where you are coming from. BUT, I look at friendship from the other end of the age spectrum. I am 61. I have a handful of friends that I can call up any time. One has been my friend since high school, one since college, one a neighbor, and one of them is a more recent friendship. Unfortunately, they live a good 10 hour drive from where I live now, and although I have lived here for 4 years, I have no one I could call to just go out.
It doesn’t mean, however, I don’t go out and do stuff. I have learned over the years (51 years in fact) that I must be my best friend. That although my friends are connected to me on a limb of life’s experiences, the breeze that brought us together may never be that strong or in that direction again. It doesn’t mean that you aren’t my friend even though you now have a family, live in a different city/state/country, or have a job/career that demands most of your time. It means that when we have a chance to meet again face-to-face that our friendship will feel like we belong together as friends.
Friendships change, but the ones that are worthwhile will transcend time and space.
