Actual conversation with Oliver on the way to school earlier this week:

Oliver: Catherine’s getting her hair cut today at her barber Blue Note.

Me: Blue Note is really more of a “hair dresser.”

Oliver: Why?

Me: Well, places where women get their hair cut tend to be called “hair dresser” instead of “barber.”

Oliver: Why?

Me: I don’t know. Although some people I know who are men get their hair cut at Blue Note.

Oliver: Who?

Me: People at silverorange like Steven and Isaac.

Oliver: There’s an Isak at my school.

Me: Yes, he spells his name differently though.

Oliver: Oh, that’s a homophone.

Me: A homophone?

Oliver: Spelled different, sounds the same.

I looked it up. He’s right. I thought it was a homonym, but it isn’t. I’ve a feeling this is the start of a long slow slide into the intellectual shadow of my son.
