     Although I had left school against the advice of my teachers, I had, without telling anyone, tried
to    1     my studies in literature at evening classes. It was a tiresome     2     from one end of the city to
another and to     3    among adults was uninteresting. I was the youngest in the     4   , so the friendship I
knew at school was     5     . I put up with it for a short period. It was    6    long a walk on cold winter's
nights and it was hard to put my    7    into Shakespeare with wet shoes and trousers. So I continued
writing poetry at home.

and    20   I realized that if I gave up my job training, it would be very difficult to get a good job. But
nothing could stop me, and they asked about the matter no further.
