The time would not pass. Somebody was playing with the clocks, and not only the electronic clocks but the wind-up kind too. The second hand on my watch would twitch once, and a year would pass, and then it would twitch again.
There was nothing I could do about it. As an Earthling I had to believe whatever clocks said -and calendars.”
