I have a problem that AI doesn't help with

So i have this ''friend'' which is not really a friend, more like a person that is in the same room as me when we are at work. So i can pretty much do anything and he will never say anything about it. <br><br>The problem is that he talks as much as possible. He literally talks 8h a day straight. I can't focus on my job, i can't listen to music, i'm not even allowed to do podcasts because it's too quiet. I'm going crazy and no one can help me.<br><br>I won't call him a burden or anything but i wish he could understand how fucking annoying he is.
