"When you are at school and learn grammar grammar is very exciting. I really do not know that anything has every been more exciting than diagramming sentences. I suppose other things may be more exciting to others when they are at school but to me undoubtedly when I was at school the really completely exciting thing was diagramming sentences and that has been to me ever since the one thing that has been completely exciting and completely completing. I like the feeling the everlasting feeling of sentences as they diagram themselves." Gertrude Stein, "Poetry and Grammar."
