so you know when you see someone in public that you just know well enough that you can't just exchange knowing glances, but not well enough that it isn't tedious for both of you to stop and chat? well how about this: for around 4.99 you can buy a simple, small bluetooth button that fits in your trouser pocket. when you get stuck in a bad conversation, simply hold the button for 3 seconds and it makes your phone ring. you and the other person now have the perfect get out of this situation: "sorry I've got to take this, great seeing you!"
