Crawford writes that she knew she had to make her children better understand that everything did not revolve around them when she was on a train in France. "I discovered – two and a half hours into the ride – a two-year-old and a six-year-old seated three rows behind me," she wrote. "I had just awoken from a delightful afternoon nap when I saw them carefully and quietly making their way down the aisle with a man who I presume was their father. The trio was whispering in deference to the many sleeping passengers (again, sleep is a huge priority for the French), even though it was about 3:00 p.m.... I've since been trying to engender the same kind of regard for the needs of society in my kids. As it is, I can barely keep them quiet on Saturday morning to let their father 'sleep in' until 8:00 a.m."
