Hanging up on people was much more emotionally satisfying when you could slam the receiver down. Pressing the "end call" button just isn't the same. Someone should invent a smart phone that you can hang up by slamming it down.
You could carry an air horn and blast people with it before pressing end.
I was thinking of an app that makes the sound of a handset slamming down followed by the sound of a dial tone (another forgotten relic)
BRILLIANT IDEA! That satisfying SMASH just felt so GOOD!
