Entrapment

Trapped! You are trapped – she set a trap for you;
she used the sweetest bait and you fell in…
or did you jump? So should I rescue you?

I have a rope that you could use to climb,
and here I have a knife, you see it flash,
and yet you don't know what the knife is for.

Now trust me, and I'll drop the rope to you;
a fit young man like you can climb right out.
You see the knife but don't know what it's for!

The rope is tied to that strong tree, you see?
Now come to me, I'll rescue you dear heart -
and when you hang suspended, near the top,

I'll show you what the knife is for.
