A story—The sunset happened an hour ago. The couple sat talking for two hours more. This was their 1st date and in Japan as the evening was soon coming to an end he brought her a goldfish from the little pond. She swallowed it. This indicated that she had a good time. The custom in Japan is if the goldfish is swallowed he can ask her on a 2nd date. On the 2nd date the goldfish is offered to the man. If he swallows it the couple is officially going steady. This is how the popularity of sushi came about in Japan.
