My cell phone rang.

Me: Hello?
Him: Hello. Who is this?
Me: You called me. Who is this?
Him: This is Chris.
Me: OK, this is Sarah. Do I know you?
Him: Is your mom there?
Me: I am the mom. Um, I think you have the wrong number.
Him: Oh, OK. Sorry.

People are weird. That's why I don't like talking on the phone.
