Cellphones in French Class

I was so lucky during French class on Wednesday. Someone's phone started ringing during the lesson and was quite loud too. Once it started ringing, the room just went dead silent. I think everyone was wondering who's phone it was. A few seconds later, the teacher found out who it was. The owner of the phone wasn't really a great student either. He always talks to other people during class. The teacher send him outdoors to have a little "chat" with him. Everyone in the classroom was still dead silent. People probably wanted to hear what the teacher was saying to him. After a while, they came back inside. The tension in the room didn't go down at all. After the bell rang, I noticed my phone started beeping. I took it out and saw that it was running out of battery. I was so lucky that it didn't start beeping in class otherwise I would've got in so much trouble.
