People who are tough never have to tell you that they are. It's the same with people who are honest. Don't squat with your spurs on. When you're throwing your weight around, be ready to have it thrown around by someone else. Telling a man to get lost and making him do it are two entirely different propositions.
Good judgment comes from experience and a lot of that comes from bad judgment.
When you give a personal lesson in meanness to a person or a critter don't be surprised if they learn it. You ain't learnin' nothing when you're the one doin' the talking. Lettin' the cat out of the bag is a whole lot easier than putting it back in. Always take a good look at what you're about to eat. It's not so important to know what it is, but you should know what it was.
