Phone Call

I had a very interesting phone call this morning.
"Hello"
"Hello. May I speak with Shirley?"
"There is no Shirley at this number."
"To whom am I speaking?"
"May I ask who I am speaking to?"
"Theresa?"
Apparently I don't speak clear enough.
"Who is this?" I ask.
I don't remember what name he said. "And who am I talking to?"
"What is this call in reference to?"
"Is this the number for (an address)?"
"No."
"Well then this is the wrong number."
"Uh Yeah!"
"Well you should change your number."
He then hung up and I started laughing. Honestly, who tells someone to change their number when they get a wrong number. People are so weird!
