Foresight and Hindsight

"Hold me tight."  You say this to me,
when you feel it slipping away.
My eyes fail to meet yours,
body slack like a smile spent.
Maybe the attention you pay
is a toll on the road to considering yourself a good person.
Or maybe you can see the resulting hypoxia when I think
you've gotten too close, and so I let go.
That's the trouble with foresight and hindsight.
They're often so hard to tell apart.
