"Never sit with your back to the door," the old Cowboys say.
ALWAYS know what's behind you.
As a matter of fact, it's ALWAYS the old Cowboys that say that and only the old Cowboys.
The young ones who didn't understand that, generally didn't grow old.
This guy survived, as he is a good friend to this day. But still...... "A word to the wise is never wasted."
That old saying is ALWAYS true because if they didn't listen, it proves they weren't 'wise'.
