(You will need a small tube of toothpaste to make this‑effective.)
Have you ever squeezed too much toothpaste out of a tube of toothpaste and tried to put it back in the tube? It can’t be done, can it? No matter how hard you try, the toothpaste is out of the tube forever. Toothpaste is similar to unkind words. Once unkind words come out of your mouth, you cannot take them back. So when you are tempted to say something unkind, remember the parable of the toothpaste, and keep the unkind words to yourself.
