Love is feeling free. When I say free, I mean being absolutely content with the exact person that you are. When someone allows you to be comfortable with yourself entirely. You don't have to change or even try.
You can simply be you, and that's enough.
That's love to me.
And, of course, my favorite:
It will not betray you, dismay, or enslave you.
It will set you free."
-Mumford & Sons
