Ok-so, have you ever been in one of those situations where you find yourself running into somebody you barely know and never established any "conversational relationship" with and haven't seen in a long time, yet AFTER SUCH A LONG TIME feel the urge to strike up a conversation with you and try and find out EVERYTHING about your life since the two of you were last in the same room together or something to that effect, but don't wanna look like a jerk for not allowing them to even get a word in?? (run-on, i know)

Well, what if there was a device that could call your phone (even if it is on vibrate the ringer will go off) but not only that, but have a recording of a friend or a close relative yelling about an emergency that the other person could hear? And it could be activated by pressing down on your big toe or something, so the other person would be none the wiser. I know I could use that thing
