"It is not true that drink changes a man's character. It may reveal it more clearly"

In this quote, John Osborne is suggesting that alcohol does not necessarily alter a person's character, however rather it brings out their true nature more prominently. This can be interpreted as a warning against the belief that alcohol can alter a person's behavior or personality. Rather, Osborne is suggesting that alcohol merely gets rid of inhibitions and allows a person's true self to be seen. This can be seen as a cautionary declaration, advising us that our actions and words while under the impact of alcohol might not truly show who we are as people. Ultimately, this quote highlights the importance of self-awareness and responsibility when consuming alcohol.
