It was Sunday．The train was crowded．A gentleman was trying to look for a place．In one of the cars he saw a vacant seat．But a small suitcase was lying on it and a young man was sitting next to it．

    “Is this seat taken?”asked the gentleman．

    “Yes, it’s my friend’s．”answered the young man．“He’s just coming—this is his suitcase．”

    “Well．”said the gentleman, “I’ll sit here till he comes．”Five minutes later the train started, but nobody came．

    “Your friend is late．”said the gentleman．“He has missed his train, but he need not lose his suitcase．”And with these words he took the suitcase and threw it out of the window．

    The young man got up and tried to catch the suitcase，but it was too late．It was a good lesson to him．“It’s impolite to take a second seat just for being more comfortable for oneself．”
