All the other male pigs on the farm were porkers. The best known among them was a small fat pig named Squealer, with very round cheeks, twinkling eyes, nimble movements, and a shrill voice. He was a brilliant talker, and when he was arguing some difficult point he had a way of skipping from side to side and whisking his tail which was somehow very persuasive. The others said of Squealer that he could turn black into white. –Animal Farm,
George Orwell

hmm, sadly there is no dialogue. there is no place in the story where he is talking to anyone. it's more of just describing what he eats and where he sleeps. you have to become anne frank, give details of where you are, what other folks look like, how the environment is. have a little bit of dialogue tell of what people are specifically saying. anne frank talked about her entire household including the people, the objects, the lighting, the food they ate, and even the smell in the air. there has to be more to your diary entries, the whole story in its current state is only about peter van daan, the food, the sounds, and where he sleeps. also he seems to be writing only once a year yet more than that happened from day to day. for a friend, i can you write it out, if you want.
