One Christmas when I was like seven years old, my great aunt Ruth stayed with our family. She was a nun and for some reason this meant that, on principle, we had to attend Christmas mass at the proper time (Christmas morning) and we were not allowed to open any presents until mass was over.
The sermon was over three hours, I had a cheap casio watch and was timing it.
I studied math and my first thought here is Gödel’s incompleteness theorems.
