Scout’s aunt’s orders are typical of her because she is a very bossy and opinionated lady.
Aunt Alexandra comes to town and immediately begins bossing people around.
"Put my bag in the front bedroom, Calpurnia," was the first thing Aunt Alexandra said. "Jean Louise, stop scratching your head," was the second thing she said. (ch 13)
Even though no one knew she was coming, Aunt Alexandra jumps right in and begins ordering people around. Her order to Calpurnia shows that she sees no need to be polite to the black servant. She does not say “hello” or “how do you do” or any other pleasantry.
I heard the suitcase hit the bedroom floor with a thump. The sound had a dull permanence about it. (ch 13)
Aunt Alexandra also feels that she has the right to tell Scout what to do and what not to do. She does not say how long she is staying. She is not the sentimental, loving or motherly type. She does not greet Scout or give her a hug. She just tells her not to scratch her head. She also uses her real name, and not her nickname. This further shows her distance from the family.
