Recently, I realized that I have very few friends. There are no more than three of them. However, I often see people who have a lot of friends, and sometimes I begin to feel somehow impaired. What do you think? Do you have a lot of friends?
As you get older, and as you develop beliefs and habits, you will lose friends.
I have two people I still talk to from when I was young - the rest come and go, sometimes for years at a time, as my situations change.
