Superposition of Silhouettes

You were practice
But I never practice hard enough
The fact is, it's easier to give up
Than to give all

So we have this superposition of two silhouettes
Where the lines match up but the shading doesn't yet
How far away can close get?

You began this
But you never finish what you start
In part it's just that it's impossible to hit the mark
When you're thus marked

So we have this dark simulation of a pirouette
Wherein the spinning doesn't stop till one of us has fled
How far away can close get?
