Come along with me on a wondrous journey of imagination.
Just suppose there is a parallel universe, almost exactly like ours with the seemingly minor difference, that being that once a month, randomly and without visible cause, skipped a day on the calendar. So today, although ostensibly the 14th might actually be the 15th?
Think about the consequences. What if you are paid on the 14th? What if it was your birthday on the 14th or you had a scheduled colonoscopy that day? Can your brain even begin to fathom the chaos that would ensue???
Try going to sleep tonight with that thought rolling around your brain! It will make the monster under your bed seem like a welcome visitor.
