@inuviate I dare you to turn to her or tap her on the shoulder if she's in front of you, and ask her "Could you please tell me the time? the clock on my phone doesn't work."
@inuviate I dare you to put your headphones on and not plug them properly into the phone, and put on your favourite song. So it will play loud on the whole bus. Or actually tell me some songs you have. Anything embarrassing?
