A friend´s problem

Last Wednesday we had class with Claudia. In that class Alvaro told us a story. The story was about a problem. This is his story. One day his parents had to come out. So he had to stay home alone. He went to the living room and began to play Just dance. When he was playing, he had to lift his hands. He broke a glass. So he had to go to the store and buy another. When he returned to his house, he realized he had forgotten his keys. So he had to wait his mom.
