I pride myself on always being on time for appointments, work, and meeting up with friends etc.. I have been doing this all my life and don't believe I will ever flake out. I'm just too fucking reliable. So my question is what causes people to become flakes? Is it a chemical inbalanace? Schizophrenia? What? How do flakes even function in society, get jobs even? I have observed people who I once knew as punctual & reliable people have become flakes, sometimes gradually or just out of the blue. Can being flakey be considered a disease?
