Their heartbeat does not define love
Their eyes do not define love
Their smile does not define love
Their presence does not define love.

What does define love is
Their actions - do they dare to leave something just for you?
Their sacrifices - do they dare to take chances eventhough the chances of both of you to last is unpredictable?

Love is when you do anything in the moment although you could not control fate.
Love is when you take that leap of faith and risk something.
Love is when you feel it is worth it to let them take something from you.
Love is when you feel you want to spend the rest of your life with them.
