It's a figure of speech, silly

Daddy is at the office.  He calls home:

Pia: Hello.

Daddy: Hello, who is this?

Pia: This is Pia.

Daddy: Where's Mommy?

Pia: She's at home.

 

...5 seconds of quiet...

 

Daddy realizes Pia was still at the other end waiting for the next question:

Daddy: Can I talk to her?

Pia: Ok. I will call her now.
