Granddaughter: It’s March 14th grandpa, national “pi” day.
Grandpa: I love pie!

Granddaughter: Not that kind of pie grandpa, I’m talking about a formula!
Grandpa: Back in my day we called it a recipe!

Granddaughter: Graaaand Paaaa, not that, it’s a mathematical formula, you know an equation.
Grandpa: That’s the problem these days, everyone makes things so complicated. In my day we used things like cups, teaspoons and tablespoons. We didn’t need math if we wanted to bake a pie.

Granddaughter: Oh, I see your point! So what would you like, apple or cherry pie?
Grandpa: Finally, a young person who actually understand things.
