Jimmy lives in London and he began swimming a few months ago. He likes swimming, and he often goes to the swimming-pool near his house with his mother and swims there for an hour or two.
He was six years old last week, and his mother said, 'You swim quite well now, Jimmy, but you've never seen the sea, have you?' Your father and I are going to take you there on Sunday, and you're going to swim in the sea. It isn't cold now, and it's much nicer than a swimming-pool.'
Jimmy's father and mother took him to the sea in their car on Sunday, and they stopped at the side of a small harbor. Jimmy got out and looked at the sea for a long time, but he was not very happy. Then he said to his mother, 'Which is the shallow end?'
