Grumpy Old Man?

I suppose it's possible to suffer from dementia at an early age. Perhaps I have turned into one of those crazy, obsessed old men... Shinning flashlights at stars... Speaking to himself (and answering)... In my youth, and even in my young adult life, I never imagined I would have changed to the point I have.  I thought I would at least hold on to some semblance of my twenties, but I am completely different than I was then. We all grow and mature. Change is part of life. To lose oneself and to drastically change almost every aspect of your life and personality, is a little unexpected though. I have turned into a cantankerous, bitter old man, in a perpetual bad mood. I talk to very few people, but when I do, my sarcasm and lack of patience has gotten much worse. What the hell happened to that laid-back musician? Where did my mind run off to? Who replaced my personality with this horrible one? And who keeps spinning the hands on the clock faster each year?
