im really pissed right now,help?

I was playing with followers and all and I mistakenly left game chat on, during that a "friend" of mine decided to turn on his to hear how sound like when I clearly tell him that I wont even reveal my voice
I was watching a video and all so he didnt hear me (I didnt speak at all either) but it pisses me off so much that he does what I tell him not to do, try to even bother listening how I sound like

anything to cheer me up even because that one thing just pissed me off so much
