Can deer read, Momma

Driving down a country road with beautiful countryside we encountered a family of deer. A couple of big ones and a couple of little ones. They were waiting alongside the road patiently. We passed them by and then the little boy turned around and saw the deer crossing the road.

The little boy then asked his Momma: how do deer know how to read? The Mom replied: Why do you ask? The little boy said: well, they crossed right where the sign said to.
