Principle Trumps Opportunity, Rock Beats Scissors

My world travelling parents returned from Italy on Saturday and now the Pope is dead.

One of their stops was in Pisa. My Dad glowed with excitement describing the city and the famous leaning tower. It was built as a 'thankyou' to Mary for letting them win a particular battle.
"Do they let people climb the tower"
"Yes, they restored it beautifully, and secured it so that it still leans but cannot fallover."
"Did you climb to the top?" "No, the crooks wanted $20 a person to go to the top"
"Dad"
"Yes?"
"You were on the other side of the world! You were right there! Now if you ever want to go to the top it will cost you $2020 because you will have to fly there first!"
"Nope, I'm not getting taken like that...
....you should have seen Florence!"
