Haha, I've been a heavy talker to myself for as long as I can remember. I never even had a best friend until 6th Grade, and for a while, we went to different schools anyway. Even when I'm not lonely, expressing yourself to yourself just lets anda get to know yourself better. It also helps anda remember just what in the hell you're going to do next. It's rather fun, I must say. It'll probably stick with me forever.
