The Importance of being Earnest

From the book:Morning-room in Algernon's flat in Half-Moon Street. The room is luxuriously and artistically furnished. The sound of a piano is heard in the adjoining room. [LANE is arranging afternoon tea on the table, and after the music has ceased, ALGERNON enters.] ALGERNON. Did you hear what I was playing, Lane? LANE. I didn't think it polite to listen, sir. ALGERNON. I'm sorry for that, for your sake. I don't play accurately - any one can play accurately - but I play with wonderful expression. As far as the piano is concerned, sentiment is my forte. I keep science for Life.
