A two-year-old girl has become our new hero after expertly shutting down a cashier who attempted to question her choice of a black doll.

Brandi Benner, the girl’s mother, took to Facebook to share the inspiring experience, describing how the cashier in Target had seemed initially puzzled by her daughter’s toy selection.

“While we were checking out, the cashier asked Sophia if she was going to a birthday party. We both gave her a blank stare,” she wrote. “She then pointed to the doll and asked Sophia if she picked her out for a friend. Sophia continued to stare blankly.

“The woman gave me a puzzled look and turned to Sophia and asked, ‘Are you sure this is the doll you want, honey?’”

When Sophia confirmed that, yes, this was the doll she wanted, the cashier added, “But she doesn't look like you. We have lots of other dolls that look more like you.”

While Brandi wrote that she “immediately became angry”, Sophia answered the cashier before she had a chance to respond.

“Yes, she does. She's a doctor like I'm a doctor,” the two-year-old replied.

“And I'm a pretty girl and she's a pretty girl. See her pretty hair? And see her stethoscope?”
