I am going to support the previous posting (and a fierce Wildean that I am) and I would pick "A Week in the Life of Algernon Moncrief".
The reason why, is because he is one of the most liked and fabulous, exaggerated, dramatic, careless, multifaceted , funny, and charismatic of the play.
From the days when he runs huge eating tabs at the Savoy hotel, and at Willis's, to the run ins with the creditors, to the meetings with his Aunt Augusta, to his bunburying around the country, to his meetings at the club, and his horrid piano lessons, he is definitely one BUSY guy from which you can cut a LOT of information!
One play that be conducive to this assignment would be Shakespeare's Hamlet. It covers many months of time and has many significant days to write about. For instance, there is the day he confronts his mother; the day of the play; the day he confronts Ophelia; the day he first sees the ghost; his final day of life. another play that would work well for this assignment might be Oscar Wilde's The Importance of Being Earnest. This play too covers many days time. From whichever character perspective you wish to speak, there are any number of significant days, like when the handbag is revealed, when the ladies declare the men "insuperable;" when Algernon impersonates Earnest and meets Cecily; and when John/Earnest and Algy dine without paying the bill.
If you have access to the play "The Crucible," I would write as Elizabeth. First you would tell about how your husband has become attractive to Abigail, a servant girl. You could then tell about how you had to talk with her and let her know that she is no longer to remain in your household. The next thing you know is that you are being accused of working with the devil by Abigail.
You get interviewed by Reverend Hale and soon the committee interviews you. Your husband admits to you that he actually had cheated on you with Abigail. Later you worry about your boys and ask your husband to take care of them and not to tell the truth about his affair.
Your husband refuses to sign a confession paper accusing others of witchcraft. He gets into trouble as well. They end up hanging him instead of you.
What a life and all because of one girl's hysteria and jealousy over you having your husband when she wants him for her own.
***** correction! it has to be a character from the play "death of a salesman"
