A lot of changes are made between the first and final drafts of a play. For example, the first draft of Hamlet’s most famous soliloquy went like this:
To be or not to be, that is the question
To be, that is the answer
At which point Hamlet and Ophelia race off to the box social and square dance the night away. I put that first draft in a drawer for three weeks before looking at it again with fresh eyes. When I finally did, the problem was immediately clear to me. Too much philosophising, not enough square dancing. God knows I soon rectified that mistake.
