My English teacher literally had this exact thing

What if you don't have a cell ph-ahahahaha, no I couldn't keep a straight face.

Unfortunately there's nothing a teacher can do to enforce this. Even with the threat of taking away points.

I thought this was common in schools?? A ton of teachers use this at mine, it's not that legendary

If they did this when I was in high school I would have been absent everyday since I didn't have a phone Haha

My teachers have this but only use them during tests

What if I don't have a phone?
