"I also found being called Sir rather silly"

In this quote, Harold Pinter is expressing his viewpoint on the title of 'Sir'. He finds it to be a silly title, and does not take it seriously. This might be because he does not think in titles, or because he does not believe it is a title that ought to be taken seriously. It might also be since he does not think it is a title that ought to be given to somebody, or due to the fact that he does not believe it is a title that should be utilized in everyday life. It might also be since he does not think it is a title that must be used to resolve someone. Whatever the factor, it is clear that Harold Pinter does not take the title of 'Sir' seriously, and finds it to be rather silly.
