They knew a lot of songs, too. They knew that doing their work cheerfully is the only way to make routine work bearable. They knew they were not going to get promotion. They knew to an inch where the rocket would land. They knocked the box to pieces. They know each other well. They know how to make an atomic bomb. They know how to swim. they know how to swim with the tide, and they’re unselfish. They know Kabyle. They know that you cannot speak English well. They know the importance of protecting the earth.
