Ajith calls the Help Desk to complain that there's something wrong with his password. No, it's not the usual caps-lock problem.

"The problem is that whenever I type the password, it just shows stars," he says.

"Those asterisks are to protect you," the Help Desk technician explains, "so if someone were standing behind you, they wouldn't be able to read your password."

"Yeah," he says, "but they show up even when there is no one standing behind me."
