One of the first similarities that was easily distinguished was the voice of the two works. Both are in the first person point of view,and each narrator is talking to themselves. They are recording what is happening to them and describing the world around them as well. However, the diction of these two characters is quite different. In Born of Man and Woman the main character speaks in a more primitive, childlike way, as if he has little intellect. In Grendel this is not the case at all. Grendel speaks surprising well, considering he had a mother who did not even talk. He seems smart and uses language well to describe his life.
Another similarity is that Grendel and the other unnamed narrator are easily sympathized with. They are both easy to sympathize with because they are not so different from people, but they are different enough that they are rejected by people. They both admire normal people and long for their companionship. They are very lonely characters because they obviously do not fit it with other people. They wish they could be normal and join the others,
