Cunning is a short blanket - if you pull it over your face, you expose your feet

Cunning men deal in generalizations.

I was sitting here on this blanket so, here's the truck - maybe 6 feet.

Pull it up by the roots

The abilities of man must fall short on one side or the other, like too scanty a blanket when you are abed. If you pull it upon your shoulders, your feet are left bare; if you thrust it down to your feet, your shoulders are uncovered.

See not the face..
but only the eyes,
of the poker face.
