To encourage them to be aware of their responsibilities, the children were expected to do their chores like any other children. They had to keep their rooms clean and even the young king had to make his own bed when he was in Lausanne. This habit remained in later years. When King Bhumibol Adulyadej was living overseas, he would drive, wash, and even polish his own car without assistance. Similarly, after his music sessions, he would insist on putting away his own musical instruments and wiping them himself.
