Knowledge: HIM, a rapper, prepared for his concert for over a year and practiced his dance 4 hours a day. On the other hand, a ring bearer as a dog should learn to walk straight slowly, which requires a lot of practice.

Conversation:
My dog is the ring bearer at a wedding.
Oh, neat! Is your dog male? If so, he could be called a page boy!
He is! Do you happen to know when page boys became common?
I don't know, but I know there could be many pages at a cotillion.
Uh huh, do you know what I should do to prepare him?

Response: Ah yes, it will require a lot of practice but a ring bearer as a dog should learn to walk straight slowly.
