What's Annoying?

While reading a book about the job of the President today, one of my students became very curious.

Ms. W: A president has to campaign to be elected.

A: What's campaign?

Ms. W: A campaign is what someone does to receive votes. They can go around and make speeches about what they would do if they were elected.

A: What's vote?

Ms. W: It's when you choose the person you like best to become something.

A: What's choose?

Ms. W: I think you're asking questions just to be silly now.

A: You know I don't know everything in the whole entire world Ms. W!

That is something that I did actually know, A. Thanks for informing me though.
