Cheating is easy. ......

Cheating is easy. 

There's no swank to infidelity.
To borrow against the trust someone 

has placed in you costs nothing at first. 

You get away with it, 

you take a little more and a little more 

until there is no more to draw on.
Oddly, 

your hands should be full with all that taking. . . 

but when you open them there's nothing there.
