Book Reports / The Metamorphosis by Franz Kafka - Monologue [4]

Hi, I've just been assigned an english project where I have to create a 5 min. monologue through the perspective other than that of the protagonist, Gregor Samsa. Being that this is my first attempt in writing a monologue, I'm having issues starting. I'm planning on writing through the perspective of Grete Samsa from chapter three till the end. I'm not sure whether I write it as if I'm reflecting back on what had happened or as if I'm presently going through the story? Any feedback would be great, thanks.
