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 .
