Dr. Johnson and His Son’s Daily Routine

Living Arrangements

Dr. Johnson resides in a ten-story tower block with his five-year-old son.

Morning School Routine

Each day, the young boy takes the elevator from the 10th floor to the ground floor to attend school.

Evening Return Method

In the evening, however, he takes the elevator only to the 5th floor and then walks up the stairs for the remaining five floors.

Reason for Stair Use

The reason for this pattern is that he is unable to reach the button for the ground floor yet.
