I lost my phone, and someone answered when I called.

The other person said, "Are you the owner?"
I said yes.
He said, "I can return your phone, but you have to answer a question."
What question did I ask?
He said, "That contact named 'Baby' in your phone, who is that to you?"
I said it's my mom.
He said, "You call your mom 'Baby'?"
I said, I have 'Baby' saved in my contacts, is there a problem?
