Your irritation was brewing as you wrote back "Who R U?" You looked outside your office to see if anyone reached for their phones, but you couldn't see anybody. Your phone buzzed - a quick reply!
"That would ruin the mystery. I have a task for you."
You needed a clue who you were talking to, so you tried to call the number that was texting you. Maybe if she answered, you could hear her real voice, then you would be able to figure out who it is! But she declined the call after one ring. It buzzed again - another text.
"Uh-uh, T. Can't fool me."
