A Damsel in Distress by P. G. Wodehouse

In his bedroom at the Carlton Hotel George Bevan was packing. That is to say, he had begun packing; but for the last twenty minutes he had been sitting on the side of the bed, staring into a future which became bleaker and bleaker the more he examined it. In the last two days he had been no stranger to these grey moods, and they had become harder and harder to dispel. Now, with the steamer-trunk before him gaping to receive its contents, he gave himself up wholeheartedly to gloom.

Somehow the steamer-trunk, with all that it implied of partings and voyagings, seemed to emphasize the fact that he was going out alone into an empty world. Soon he would be on board the liner, every revolution of whose engines would be taking him farther away from where his heart would always be. There were moments when the torment of this realization became almost physical.
