Due to an incident that happened when you were younger, it left you mute

You usually use your phone to help you communicate, but you left it alone for one minute, and it got stolen.

The teacher, not knowing this, called on you to answer the question, but you didn't know what to do without having your phone to communicate. Suddenly, Walker, your bully, said something

"He doesn't have his phone. Choose someone else."

Walker said, which was quite the contrast to his usual behavior.
