We learn that even the one person that wasn't supposed to ever let you down probably will.
You will have your heart broken probably more than once and it's harder every time
You'll break hearts too, so remember how it felt when yours was broken
You'll fight with your best friend. You'll blame a new love for things an old one did.
You'll cry because time is passing too fast.
And you'll eventually lose someone you love
So laugh too much and love like you've never been hurt.
Don't be afraid that your life will end, be afraid that it will never begin
