The Importance of Being Earnest (Miss Prism)

Miss Prism says

Cecily! I am surprised at you. Mr. Worthing has many troubles in his life. Idle merriment and triviality would be out of place in his conversation. You must remember his constant anxiety about that unfortunate young man his brother. I do not think that even I could produce any effect on a character that according to his own brother’s admission is irretrievably weak and vacillating. Indeed I am not sure that I would desire to reclaim him. I am not in favour of this modern mania for turning bad people into good people at a moment’s notice. As a man sows so let him reap. You must put away your diary, Cecily. I really don’t see why you should keep a diary at all. Memory, my dear Cecily, is the diary that we all carry about with us.
