Bella: "You know how girls make groups of 'sassy threes'?"

Kat: "I'm not sure what you mean."

Bella: "You know, like, when they are just a group of three girls and they don't want to be friends with anyone else and they act really sassy?"

Kat: "Yeah. Sadly, grownups do that too."

Bella: "Well, these three girls were acting like they didn't want to be friends with me because all three of them were black and I'm not. So, I said, 'Guys, I thought we all decided a long time ago that black people and white people can all be friends!' I thought that was really rude."
