Granulocytes. Granulocytes are the most common type of white blood cells present in the human body which account for almost 70 -75 percent of the WBCs. The reason for such a name of these cells is because they contain small and visible granules within their cytoplasm.
To extrapolate character traits, you can use direct characterization as well as indirect characterization. Indirect characterization occurs when the author describes behaviors and reactions in the character. From such behaviors and reactions, the reader can deduct more facts about the character than the author lets on. From this excerpt, you can deduct that Mary is submissive to her husband.
The term characterization was introduced in mid 15th century. This view was reversed in the 19th century, when the primacy of the character, that is, a character-driven narrative, was affirmed first with the realist novel, and increasingly later with the influential development of psychology. Direct vs. indirect.
