The Mouse<br>Ashley had been working for twelve hours straight. Her hands were getting tired from typing and using her mouse. Her boyfriend brought her a gift. It was a new mouse! It was large and easy to hold and made her hands feel better.
Ashley's new mouse was a rodent
Ashley's mouse was a computer mouse, not a real life mouse, so it is not a rodent. The system likely could not tell the mouse was an electronic mouse and assumed it must be a rodent.
