What is LOVE?

I've read this girls blog for about a year now.  I love her posts.  And yesterday she wrote this:
Love is simple.
Love is unique.
Love is endless.
Love is patience.
Love is learning.
Love is growing.
Love is fear.
Love is hope.
Love is dreams.
Love is small.
Love is big.
Love is a boggy nose.
Love is spending hours holding that crying baby doing everything to help them feel better.
Love is sickness.
Love is health.
Love is helping your baby poop because she cant get it out herself.
Love is spit up down your shirt.
Love is late night steam baths when someone gets a cold.
Love is sitting next to you in a hospital bed.
Love is never leaving even when I'm a blubbery mess because I know you need me.
Love is selfless.
Love is letting go.
Love is your future.
Love is forever.
So it got me thinking.  People think love is when you find this guy in High School or Junior High and you think he is the world, he wins you over by writing you love notes.  In most cases that isn't always correct.  To ME, love is so hard to explain.  I love my kids so much that I will never be able to explain it to them.  They will kind of know what I mean when they have kids of their own.  I love my Husband so much and I can't imagine my life without him, even though at times I want to scream at him (and I do).

But when I really figured out how much I loved my Husband was when he came out of his 14 hr open heart surgery and I had to look at how beat up he was.  While he was lying there without a clue that he was in the worse shape of his life.  I realized that I loved him more than I thought I could.  I realized that I wasn't going to be okay if he wasn't.  And I realized that truly LOVE is fear, sickness, health, big and forever. 

So what is LOVE to you?
