In terms of friendships I feel you -- but sometimes friendships go beyond just work or fighting. I'm sure Krillen had a ton of BBQs with Goku. I don't get to see my best friend all that much, but when I do, the connection is the same. I guess I kinda hope that's how it is for those characters too.
Life is a tapestry where people weave in and out. Admire the beauty of when people are together, and try not to lament when they are apart.
Would you follow a blind man?
