Why do I love you so much?

It can't be that your eyes are always smiling, even when your mouth isn't.
It can't be that you have the cutest dimple ever.
It can't be that a hug from you makes me feel so special and loved that I never want to let go.
It can't be that I could talk to you for hours about the most nonsensical topics and never be bored.
It certainly can't be that you are the one person who has fully understood me, on every level.
