I'm pissed at my friend for being on his phone during my class speech
Why does he need to listen to you?
I ask all my friends to take part in an action that's helpful to me and then he just doesn't take it well and still be on his phone texting nonsense
You are right, your friend is being very inconsiderate about your speech. He can use his phone any time else when he should be listening to you. The disrespect is enormous and you need to address that or he'll keep doing it.
Fine I'll tell him, who knows we might get into a fight.
If you talk to him in a civil manner I'm sure he will understand your point of view. Tell him how rude of him to use phone while you were giving speech.
