This morning

Today I was in the hallway outside of my parents' bedroom. I could hear my dad calling my name, so I went in to see what he had to say.

"Christine, this is a big day for you. I figured it out. Today you are exactly one quarter of your way to 90."

Later he realized that really I'm actually three months away from being a quarter of the way to 90, but I was cracking up even that that had occurred to him.
