Ever drive yourself nuts waiting for a phone call?
Check your phone incessantly?
To make sure that it's ON?
Still accepts incoming calls?
Hasn't lost it's battery?
Chain yourself to your desk waiting? (even though you have a cell phone that's, well, portable?)
Put your cell phone in your pocket so you can get up and get a drink, but then worry it won't ring because it's upside down?
Refrain from going to the Ladies' Room because cell coverage could be a little spotty in the stall?
Check your phone one more time because, well, it might spontaneously shut off because you're talking about it?*
*What? It totally could!
