I liked this quotation in particular: You can never really determine during their appearances in public that their private life is full of hell and unhappiness. . . . I have found time and time again that travelling together is a real test of a friendship or a relationship.My observations indicate that the majority of vacationers spend their time in misery. They fight about money; where to visit. . . . All their aggressions somehow are immeasurably increased, and this is the time they discover they are not properly matched. Women especially have a difficult time adjusting to both the new surroundings and their husbands. Vacations produce all the anxieties within mankind to come forward during this time, and to perpetuate the worst of emotions. . . .
