Whoever postulated this is very wise...
"To have friends, you must be a friend."
Even here in the city where I grew up and where I now reconnect with people I knew in highschool, all it takes to rekindle a friendship is to be a friend; to pick up the phone, send an email, arrange some time to spend some time together. We may not have much in common after ten years living separate lives, but just to share our lives gives us something in common: We are living in a world and sharing our lives in this world with each other makes us friends again.
These are also very wise words...
"Nothing is lost forever"
Let us be friendly.
Let us be friends.
