If you can..

If you can start the day without caffeine
If you can be cheerful while ignoring aches and pains
If you can resist complaining
If you can stop yourself boring people with your troubles
If you can be grateful every day for the food you are offered
If you can understand when loved ones are too busy to give you time
If you can overlook it when people take their fustration out on you
If you can overlook it when, although through no fault of your own, something goes wrong
If you can take criticism and blame without resentment
If you can face the world without lies and deceit
If you can conquer tension without medical help
If you can relax without taking alcoholic substances
If you can sleep without the aid of drugs

You are probably a dog or a cat.
