"Have you ever heard the tale of the wood plank and the nails? Well, imagine the nails as an explosion of temperament, an verbal agression or an insult, something like that. Imagine the wood plank as a person you know. You may nail the wood plank with your mistakes. With time you can take the nails out of the board. But in their places you will find holes, plenty of them.. and the wood plank will be not same as when you found it."

"Such things happens with people. They also nail themselves, making scars that cannot be restored. So they must preserve the wood plank of each other, trying not to ruin it with holes..Well, the tale is something like that.."
