Turn your ringer off in class

The girl I was sat beside in class today had her iPad out and was switching between texting and note taking the entire class which is fine u do u but every time she re opened her note document all I hear is “ding” like at least every 1-2 minutes. Like girly pop you are staring at your screen why do you also need to hear when you get a text. I thought this was common sense and courtesy but apparently not so ya just turn your ringers off people 👍
