There’s no telling what your roommate, your mom or your pet will decide to do while you’re in class. There will be times when all your good intentions to create a quiet space for class become disrupted. It happens. You can’t control everything!
What you can control, however, is your microphone. It’s best to just remain muted. When asking a question or participating, unmute yourself for as long as you need, and then remember to mute again.
We all understand that mistakes happen. So if you do accidentally share a little too much with the class (i.e. a loud brawl with your brother), simply apologize, mute yourself, and try to keep it from happening again.
