It's a fairly preachy book, but it doesn't really explain what it is she's doing wrong or whether she's aware of it. And then it doesn't really deal with the consequences. It's kind of like "Sam, Bangs, and Moonshine" except that where SBM has kind of an over-the-top consequence, this book really doesn't have any consequence.

Your imagination is always better than reality. Or, reality/growing up sucks.
