What is love?

I recently saw a post on tumblr about what children thought love was, here are a few I enjoy:

“Love is when your puppy licks your face even after you left him alone all day.” Mary Ann – age 4

“My mommy loves me more than anybody You don’t see anyone else kissing me to sleep at night.” Clare – age 6

“Love is when my mommy makes coffee for my daddy and she takes a sip before giving it to him, to make sure the taste is OK.” Danny – age 7

I just thought it was cute :3

I guess my definition of love is when you fall asleep thinking about the one person that makes you happy. Or when everything you dislike about that person, is exactly what you love.

So now I'm wondering, what is your definition of love?
