" Tom," she said, faintly, far away, "in the Southern Seas there's a day in each man's life when he knows it's time to shake hands with all his friends and say good-by and sail away, and he does, and it's natural-it's just his time. That's how it is today. I'm so like you sometimes, sitting through Saturday matinees until nine at night when we send your dad to bring you home. Tom, when the time comes that the same cowboys are shooting the same Indians on the same mountaintop, then it's best to fold back the seat and head for the door, with no regrets and no walking backward up the aisle. So, I'm leaving while I'm still happy and still entertained. "
