"Take any day. Next is the day 2 days before that. And next is the day 2 days before that and so on" Says Grandpa
"That is your sequence? What is that related to?" I ask
"You tell me. Use your imagination. Think out of box. Take a leap of faith. I will give you a hint. Pope." Said Grandpa.
Hmm. I started thinking. Monday-Saturday-Thursday-Tuesday-Sunday-Friday-Wednesday-Monday again and so on. Pope??
What is it that relates to those days in that order?
