(An older customer with a very old laptop approaches me.)

Customer: “Can you help me? I upgraded to the new Windows 7 thing and it’s going really really slow. Do I have a virus?”

Me: “I’ll take a look, but have you considered running Linux or moving back to Windows XP if you still have it? Your computer’s probably slow because it’s not new enough to handle the more intensive new operating systems.”

Customer: “But Linux is made by atheists!”
