It's rude to use your phone while in class.
Dan is in history class with his mobile phone in his pocket when it starts to ring.
Dan wants to respond to the phone rining.
Dan takes the phone out his pocket and silences the ringer and apologizes to the class.
"Dan takes the phone out of his pocket and answers the phone with a ""hello?""."
Dan's teacher is happy that Dan turned the ringer off and lets him off with a warning.
Dan's teacher gives him a death stare as she watches him take a call in the middle of her lecture.
