There are a select few characters of mine who are nearly as old as I am. They have remained fairly consistent and true to form even after years of refinement. Unfortunately these same character I have almost no means to incorporate into roleplaying topics. Uniquely, there seems to be some relation to the age and evolution of such characters that at some point they gain a semblance of agency, to the point writing for them is at best described as "channeling" their mindset and activities. I suspect that is because I have been portraying them for several decades.
