Today the dog ran across my key board. Don’t tell me this hasn’t happened to you. A couple of boxes opened on my screen and I did what my computer genius always tells me to do. I x-ed out of them. I didn’t even read them. When I began typing again, my o’s appeared as 6s on the screen. A gh6st had taken 6ver my computer. I carried the lapt6p t6 my c6mputer genius. Take my word that he is a very smart man. He discovered k’s were 2s and i’s were 5s. An evil, ev5l gh6st was in the machine. I finally understood my friend’s high-maintenance daughter. I wanted to run thr6ugh the house, screaming and pull5ng at my hair. Instead I hid out upstairs. My computer genius opened up a screen keyboard, and went exploring. After some length of time, he told me he had fixed my problem, though he was a bit chagrined about saving the day.
You already guessed it, didn’t you? The dog had pressed the Num Lk key.
