What do you Say?

What do you say to a friend(s) that you know are hurting so badly that no words on this earth can ease their pain. You would give anything to take that pain away but you know you can't. You truly understand their pain and why, but you feel helpless because all you can do is stand there. You see in their eyes the pain but you also see the love, joy and laughter. So for the words that I don't say please know that I love you and am here with a big hug.
