The Trumpet and the Vacuum Cleaner

The wall between 4B and 4C is thin. Iris plays the trumpet in the evening. Tom uses a loud vacuum cleaner at six in the morning. They write angry notes. Sixteen notes! Then Tom writes: "I have a baby, Mimi. She sleeps only with the vacuum cleaner on." Iris writes: "I did not know. Come at nine. Bring Mimi." Iris plays a soft song. Mimi sleeps in four minutes. Tom sleeps eight hours.
