How Important is a Friend?

How Important is a Friend?  How important is it to BE a friend?  What IS a friend?

Are we a rock or an island?  (I love that song)  "and a rock feels no pain and an island never cries... "  

Who would you be if you had no friends?  If you weren't a friend to someone else?

What I do know for certain is this:

I do not want to live as an island anymore.
