A Curious Thing

I always have a book by the bed and like to read before turning the light out. This isn't about the book or reading it is about the strange occurrence of time. It has happened many many times. I decide it is time to put down the book and turn out the light and the time is 10pm, exactly. Now you are saying I'm peeking at the clock and know what time it really is but no that couldn't be further from the truth. I may read a couple pages, a chapter or several chapters, when the eyes start closing I fold up the book, look at the clock and bingo it is 10pm, exactly. Sure there are times when it is 9:50pm or 10:20pm but the number of nights when it is 10pm exactly is freaky or surreal and it has been happening for years.
