I am notorious for not being able to find my phone. I can have it in my hands one minute, and not know where it is the next. You'd think that by now I'd keep it in my pocket or put it in its own designated spot but noo. I just put it places--nooks, on top of black shirts, under a table.
I usually have The Dude call the phone but what if I don't have him one afternoon? Then what?

You just put in your number and it calls your phone for you. Seems kind of sketchy, but the image/idea is nice :)
