(I had this conversation recently with a lady who swore she had been using computers since forever.)

Tech Support: "All right. Now click ‘OK'."

Customer: "Click ‘OK'?"

Tech Support: "Yes, click ‘OK'."

Customer: "Click ‘OK'?"

Tech Support: "That's right. Click ‘OK'."

Customer: "So I click ‘OK', right?"

Tech Support: "Right. Click ‘OK'."

(Pause.)

Customer: "I clicked ‘Cancel'."

Tech Support: "YOU CLICKED ‘CANCEL'???"

Customer: "That's what I was supposed to do, right?"

Tech Support: "No, you were supposed to click ‘OK'."

Customer: "I thought you said to click ‘Cancel'."

Tech Support: "NO. I said to click ‘OK'."

Customer: "Oh."

Tech Support: "Now we have to start over."

Customer: "Why?"

Tech Support: "Because you clicked ‘Cancel'."

Customer: "Wasn't I supposed to click ‘Cancel'?"

Tech Support: "No. Forget that. Let's start from the top."

Customer: "Ok."

(I spend the next fifteen minutes re-constructing the carefully crafted setup for this lady's unique computer.)

Tech Support: "All right. Now, are you ready to click ‘OK'?"

Customer: "Yes."

Tech Support: "Great. Now click ‘OK'."

(Pause.)

Customer: "I clicked ‘Cancel'."

(And people wonder why my mouse pad has a target on it labeled "BANG HEAD HERE.")
