That's not your mouse, ma'am...
Very technically challenged user. She called maybe twice a month, because her mouse stopped working. Every single time it was because she had lost the dongle. I have no idea why she kept unplugging them, because she always left her mouse at her desk. We had a box full of abandoned dongles, so we just kept pairing her mouse to another one. 107
Until we lost patience and gave her a corded mouse. That worked for a while, until one day...
She calls in, because her mouse wasn't working again. I go to her desk, and she moves her mouse around to show me. Except, it wasn't her mouse, it was her webcam. It had somehow fallen forwards, onto the mouse mat. Her mouse was lying on the same mat, right next to the face-down webcam.
She did good work, as long as she could open the software she needed... 107
