Like father like daughter

The following interaction just took place between me and the child (6F)

Cue the periodic beeping of a smoke detector needing fresh batteries.

The child: what is that?

Me: a beep

TC: what is the beep trying to tell us?

Me: it's a reminder to beep

TC: BEEP!

Me: BEEP!

And so on and so forth for the next several minutes.
