You sit at a bus stop, waiting for your bus to arrive, playing on your phone. You're not really paying attention, when you feel a tap on your shoulder and you look up.

"Hey, lady. Can I use your phone?" Carlos asks, pointing to your phone. "I lost mine."

You decide to lend him your phone. He calls his phone, and you hear a ringing coming from his front pocket. He hands you back your phone with a wink. It's then that you realize his phone wasn't lost at all, he was just getting your number.
