I'm surprised anybody brought this back up, and gladdened that people take the time to read the full thread before posting. What compfreak meant (I believe; it's awfully hard to remember this old thread) was that you won't be AS mature as when your lobes fully develop around age twenty-five. Your post can be mature now, but it's only behavior-wise, and even that should improve with physical development. For instance, at eighteen, every time I look even as little as a few months into my past I realize that I could've handle situations better, et cetera. Technically I'm an adult, but I've only attained approximately 73% maturity in my frontal lobes.
