Don't inquire into a person's past. Take the measure of a man for what he is today

Never steal another man's horse. A horse thief pays with his life.

Defend yourself whenever necessary.

Look out for your own.

Remove your guns before sitting at the dining table.

Never order anything weaker than whiskey.

Don't make a threat without expecting dire consequences.

Never pass anyone on the trail without saying "Howdy".

When approaching someone from behind, give a loud greeting before you get within shooting range.

Don't wave at a man on a horse, as it might spook the horse. A nod is the proper greeting.

After you pass someone on the trail, don't look back at him.  It implies you don't trust him.

Riding another man's horse without his permission is nearly as bad as making love to his wife.  Never even bother another man's horse.

Always fill your whiskey glass to the brim.

A cowboy doesn't talk much; he saves his breath for breathing.

No matter how weary and hungry you are after a long day in the saddle, always tend to your horse's needs before your own, and get your horse some feed before you eat.

Cuss all you want, but only around men, horses and cows.

Complain about the cooking and you become the cook.

Always drink your whiskey with your gun hand, to show your friendly intentions.

Do not practice ingratitude.

A cowboy is pleasant even when out of sorts. Complaining is what quitters do, andcowboys hate quitters.

Always be courageous. Cowards aren't tolerated in any outfit worth its salt.

A cowboy always helps someone in need, even a stranger or an enemy.

Never try on another man's hat.

Be hospitable to strangers. Anyone who wanders in, including an enemy, is welcome at the dinner table. The same was true for riders who joined cowboys on the range.

Give your enemy a fighting chance.

Never wake another man by shaking or touching him, as he might wake suddenly and shoot you.

Real cowboys are modest.  A braggert who is "all gurgle and no guts" is not tolerated
