Scout is a tomboy through and through. She hates wearing dresses, loves wearing her overalls, frequently gets herself quite dirty, and hates to walk away from a fight. Rolling around in the dirt while overcoming an opponent--a boy, of course--seems a reasonable response to conflict for Scout, until her father makes her give it up. Scout also likes to swear, from time to time, which earns her occasional correction from the adults in her life.
Scout's reaction to her aunt's ideas as to how a girl should conduct herself shows Scout's love of her tomboy self:
Aunt Alexandra was fanatical on the subject of m attire. I could not possibly hope to be a lady if I wore breeches; when I said I could do nothing in a dress, she said I wasn't supposed to be doing things that required pants. Aunt Alexandra's vision of my deportment involved playing with small stoves, tea sets, and wearing the Add-A-Pearl necklace she gave me when I was born . . . . She hurt my feelings and set my teeth permanently on edge . . . .
Wearing dresses is a challenge for Scout, but giving up fighting is sometimes impossible for her. She walks away from a fight with Cecil Jacobs (the first fight she has ever walked away from), feeling "noble," but three weeks later she beats up her cousin Francis, bloodying her knuckle in the fray. Scout's only comfort as she moves through her tomboy stage is knowing that her father likes her just the way she is.
