How we cite our quotes: (Paragraph)
Quote #1
I wasn't even pretty or nice like my older sisters and I just couldn't do the girl things they could do. (2)
The narrator has different abilities and interests than her sisters, which she attributes to the fact that she looks differently. The other girls are "pretty," which by the narrator's logic leads to them being "nice" and doing "girl things." Thing is, we see her sisters act pretty nastily—which is neither "pretty" nor "nice" in our book.
Quote #2
My hands were too big to handle the fineries of crocheting or embroidery and I always pricked my fingers or knotted my colored threads time and time again while my sisters laughed and called me bull hands with their cute waterlike voices. (2)
Okay, that's just mean. The narrator's sisters are supposedly "pretty" and "nice" (see the quote before this) but they don't seem nice at all—instead of helping the narrator, they call her "bull hands." Again the character is boiled down to her appearance as her trouble with sewing is blamed on her bodily appearance.
Quote #3
So I began keeping a piece of jagged brick in my sock to bash my sisters or anyone who called me bull hands. (2)
Bet you never saw a bull carrying a brick in a sock. The sisters' insults are obviously very hurtful to the narrator—so much so, that she reacts with extreme violence. Beauty may only be skin deep, but being told you're not beautiful can hurt to the core.
