In alluding to the fact that she’s “been around for a while,” Lettie essentially admits that she’s been alive for much longer than 11 years—even if she has physically been an 11-year-old the entire time. This suggests that Lettie may be at an odd crossroads: she seems wise beyond her years and as though she’s seen far more than a normal 11-year-old, but it’s still possible that she has the maturity of a preteen. However, it’s significant that obscures what’s actually going on with the neighbors at Caraway farm. The husband likely thinks that his wife is earning money through sex work, but Lettie may think the narrator is too immature to grasp this. In this case, then, she’s taking on the role of an adult to protect the narrator.
