One thing I notice in this world is that things change over time. You have people you think you'll be friends with forever, and they move away,move on in life,and things aren't as they were. Even families, they "branch out" to different parts of the country,you might only see them very occasionally."Phases" of your life come and go.Also, with time you find out many you knew died.{"For your life is like a vapor, that appears for a while, then fades away."}That's in this world.Now, eternity.When we see each other in eternity,we won't have to say "goodbye" any more. Noone will move to a place we "can't get to". Noone will die,Things won't change to the extent that we're no longer in friendship with each other.And that is the difference...
