One time I'm on the phone with a client struggling with his Internet installation CD. After several unproductive and frustrating minutes I ask the client to close all the windows on his desktop in order to start from scratch. Client says "hold on for a minute" and I'm left there on the phone waiting for him. After about 3-4 minutes Client angrily comes back on the phone breathing hard and says "ok I've closed all the windows in the house, now what?" I looked at my fellow workers out of despair wondering how the human civilization had managed to survive throuhout time.
