My Evil Twin

Recently been accused of nattering Guess old age has finally caught up But when I stop to think about it I've been nattering since I was a pup I'm really the only one listening So I've really got a built-in crowd Amazing are the stories I tell myself Sometimes I talk out loud People often stop and stare Like I'm some strange kind of kook When having conversations with myself Most passersby get spooked Take me or leave me it's who I am I'm happy in this skin that I'm in Can't change the person I am inside Perhaps I'm my evil twin
