The people in front of me with their phones are so annoying I'm going to tell them to put them down.
Why are they so annoying to you?
The light from them is bothering me.
I'm sorry the phones are bothering you, but the people using them have the right to use them. I'm afraid that you have to learn to deal with it.
If people are annoying me, I have the right to say something about it.
I know that you're frustrated, but it's difficult to tell others what to do. Try to remove yourself from a situation if it's frustrating and overwhelming for you. It will help you calm down.
