Heard all day long

Heard all day long in my house:

What are you doing?

What's that?

And it is not like they are just asked once.

Addison: Mommy, what's that?

Mommy: That's a drum.

Addison: Mommy, what's that?

Mommy: That's a drum stick

Addison: Mommy, what's that?

Mommy: That's a drum, see you use the stick to hit the drum.

Addison: Mommy what's that?

Mommy: It's a DRUM.

Addison: Mommy what's that?

Mommy: Go ask daddy.
