I am in a school that resembles my children's school. I have to take a test and simply write an X next to names. Every now and then I slip and type other letters. A man comes and gives me more sheets of paper. On one of them I recognise mathematical formulas with L and A. I wonder if I can still solve these exercises. The man leans on the table and laughs heartily at the music we have never heard before. Suddenly, I am afraid that a simple X next to the names is not correct or sufficient. But the man reassures me and says that it will count. He continues to lie on the table laughing, and I ask him if I should get him a cup of coffee.
