“Doctor is this going to hurt much?” the terrorized patient asked Mariluz Leَn, the dentist at the “Happy Teeth” clinic who, a little impatient, was waiting with a drill in her hand. “Of course it won’t, dear, you won’t feel a thing!” she answered trying to calm him down. “Listen, this is how we are going to proceed, take this tube of toothpaste in your hand and, if it hurts too much, squeeze the tube a little to calm yourself down.” The doctor started the drill and even before putting it into his mouth, the patient squeezed the tube so hard that toothpaste splattered on the ceiling and the doctor found her face covered with it as if someone had thrown a pie in her face.
