One day, Mr Read and his son went out for a walk. He put on a pair of shoes together with a pair of different socks, one white and one yellow. As he came out of his house, his son noticed (注意) the colours of his father’s socks and said: “You have put on two different socks, Dad.” Mr Read found his son was right. He was happy and said: “What a clever son, go back to the house to get another pair of socks for me.”
When the son went back, he could find one white sock and one yellow sock. Then he took the socks to his father: “It’s no use changing! These socks at home are also different, one yellow and one white.”
