Being on the receiving end of someone else's impatience gives us a first-hand experience of what others experience if we are impatient with them.

Doesn't it feel distressful to be rushed by an impatient clerk? Isn't it irritating when someone you call up for instructions or to register a complaint is too impatient to hear you out? Isn't it annoying when you're going as fast as you can and someone yells, "Hurry up already!"
