Once I had to read a text-book which was so expensive for me to buy it. I couldn’t obtain it from the library and an only copy I could find was in a certain bookshop. So I will go along to the shop every afternoon and read a little of the book in a time. One day, therefore, I was disappointed to find the book missing from its usually place. He was about to leave when the owner of the shop waved at me. Expecting to be told off, I went towards him. To my surprise, the owner pointed to the book which placed in a corner. “I put it there in case it should be bought.” He said kindly, left me to continue my reading.
