hay que pensar muy bien en todo antes de actuar, 
arrepentirse significa tardar en rectificar.

Well you only need the light when it's burning low
Only miss the sun when it starts to snow
Only know you love her when you let her go
Only know you've been high 
When you're feeling low
Only hate the road when you're missing home
Only know you love her when you let her go
And you let her go.
