Why don't the Japanese do away with this old custom of seeing people off? To be frank, it is a great waste of time and energy, and is meaningless. Seeing-off, like photography, is one of Japan's national sports. I have come to the conclusion that the 5 Japanese are lacking in imagination and unable to put themselves into the other person's shoes. People go to seeing-offs as to a party or a show, where the person being seen off is subject to endless snap-shotting and present-giving. Especially when a person is traveling by air and luggage is limited to a certain weight, it is 10 foolish to force presents on the helpless traveler, who is obliged to pay *extra for the *excess luggage. ? Actually I can't help feeling for the person being seen off, who must spend his last precious hours bowing and smiling, being photographed over and over again, and saying meaningless 15 things. > *Leave-taking should be a *solemn moment shared, if at all, 17 with only one's dearest friends
