why do taylor and turtle like mattie

Mattie is a savior of sorts. Mattie is a grandmotherly woman who assists Taylor when she first arrives in Tucson, Arizona with punctured tires. Mattie immediately realizes that Taylor is a new mother and gives her advice on Turtle, and eventually she even gives Taylor a job at Jesus Is Lord Used Tires and helps Taylor conquer her fear of exploding tires. Mattie runs a sanctuary for refugees from South America, and it is she who houses Estevan and Esperanza along with other illegal immigrants. When Mattie cannot find a reasonable way to transport Estevan and Esperanza to another safe house farther away from the border, Taylor offers to transport them while going to Oklahoma to establish guardianship over Turtle.
