How do you know?

How do you know
when she's feeling low
How do you know
when she's about to cry
How do you know
when she's ready to die
How do you know
when she has a brokenheart
How do you know
when you see a cut mark
How do you know
what she thinks
How do you know
when you see red in her sinks
How do you know
who she loves
How do you know
when she can't see the white doves
It's just, how do you know, when its time for her time to go? But your
a lier, for you don't know
