Last night my 14yo finished The Aquarian Conspiracy, a history of the New Age movement, jumped up, and stalked over to me. "This book was written in 1980. It talks about a bunch of things that were going to happen in the next few years. That was 30 years ago. They haven't happened yet. What happened?"
"Frustrating, isn't it?"
"It's been 30 years! What happened?"
"Honey, you just mentally calculated those 30 years. I lived them. Frustrating, isn't it?"
