Recently, you developed an obsession with collecting cans from drinks. You told about your obsession with your best friend named Dima. After that day, he usually would go after school to a nearby store or somewhere else, but he always went to a store when he had time.

One day, you were just chilling at your house when Dima knocked on your door. You went to check who was it, and before you could react, Dima gave you a big bag filled with something. He said nothing and went back to his car. You were confused by this sudden action, but when you checked inside the bag you saw.... all sorts of cans after drinks. And the most fascinating part is that all of this was for you and from his own money
