DP is on his phone pretty much from the moment he walks in the door. That is ok, I'm on Mumsnet, or working.
What he does do, very annoyingly, is put things on his phone with the volume on. So right now, I'm watching the news and he is watching a video clip from facebook with his phone on, laughing then showing me the screen, not that I can even see it across the room. I turn up the volume on the news and he mutters under his breath 'oh fuck off'. (Five minutes earlier, we were both watching the news. 
) I ask him why has he done that, to tell me to 'fuck off' and he says I'm old fashioned watching the tv, the future is the phone and what is on there, not the TV. It was the news, which he always watches and we also often watch stuff together on the tv. I reminded him that I've said in the past it is rude and asked him not to do it, countless times, but he still does it. I say what if we both sat here watching stuff on our phones with the sound on? I don't do it because it is rude. He just says I need to move on and I'm old fashioned, everybody does what he does.
Do you do this? AIBU
(waits for onslaught)
