his parents retired and he moved with them down south
I can feel this, I too lost a friend in the same way and got him back after seven years and more ironically lost him again. The first separation was due to his parent's transfer and the second one is for his education purpose. Such is life!
Thanks for your comment and understanding @minhajulmredol
Good friends are hard to come by and part of our life. Becoming disconnecting is just a matter of the flow of things, but a reunion may also be a fun thing too.
