I agree with some of you as far as a few of the language inconsistencies go, however a few can be explained by simply rereading the parts of the book you couldn't make sense of the first time. Exa: It would be weird that the two year old Mae Mobley was potty trained before complete sentences, if it wasn't also noted that her mother refused to spend much time or hands on with her daughter- including with the potty training, and physically showing Mae how to get the job done, therefor, Mae was probably past being ready, and behind with her training until finally being shown by her maid, who it says, had mentioned that Mae's mother refused to do so herself.
I also flipped past a few sections that seemed to drag, but all in all, I think most will find it an enjoyable read, though I do wish the author had included more of an ending.
