The future is madness
One of the issues my grandfather had when he was well into his mental decline was a firm belief that the people in the TV were watching him. It's a little concerning that when the same thing eventually happens to me, no-one will actually notice since the things that used to indicate a serious detachment from reality are now just a common part of everyday life. I just need to make sure I have enough cats that the imaginary ones don't stand out, and I'll be completely prepared for my gentle descent into insanity.
