I don't know if you call this losing friends or not, but I have failed to deepen any friendships in the last thirty or forty years. I only have one close friend that I have known for over 50 years. I know a lot of people and there are a few that are friends, just not close. I blame a lot of that on BP because it alters what others perceive as my personality, which is either a silent brooder or a boastful blowhard. I don't want to be either of those things but I am both.
