John needed to buy some food, that's why he went to the supermarket.
 "Oh, there is so much food!", — John thought, — "I don't know what to buy … ."
 Suddenly, something bumped into his trolley, and vegetables, loaf of bread and a packet of milk fell on the ground.
 "I'm so sorry!", — the person said, — "My trolley got broken, that's why … ."
 "Oh, no, it's my fault, I was very far away in my thoughts … .", — John answered.
 Finally, he looked at the person near him. "James!", — he exclaimed, — "I don't believe it's you!"
 "John! Long time no see!"
 The two men burst out laughing.
 John said: "Do you remember, when we were schoolboys, we had our own music band?"
 James: "Oh, yes! These were lovely days".
 John: "Maybe, we can start singing again? I called Dan yesterday, he wants to play the guitar again … ."
 James: "I think that is a great idea! Let's go to the music shop!"
 John needed to buy some food but bought nothing of it.
