If you take a mouse to school, he will likely cause mischief and disruptions throughout the day. The mouse will get into your lunchbox when given the opportunity and may try to participate in classroom activities like science experiments or playing with building blocks, despite not being a student. When the school bell rings, the mouse will also not follow typical school routines and may ask students for their lunchboxes. Bringing a mouse to school is generally not recommended as it will not behave appropriately for a learning environment.
