Sometimes, my DH waffles on throughout a programme he is watching, when I am trying to concentrate on something I am reading or writing. Either when I am writing something or reading something on the computer/the internet, or when I am reading a book or magazine.
He even does it when I am doing something that is part of my actual JOB. When I am in another room, working, and he is at home, he comes in telling me about the latest episode of whatever he is watching, and gives me a synopsis!
I DO NOT CARE! 
It does my fucking head in. I say 'you don't need to narrate the show, or give me a synopsis of it... I am not watching it, I am not interested.'
He sometimes says (indignantly) 'well I am interested .. ' Like I should be a good iccle wifey and drop everything I am doing to listen to him chatting shit about the programme HE is watching - that I give zero fucks about. I say 'Well I am NOT and I am trying to concentrate on something else. FFS!'
I sometimes even put my headphones in, and say 'I am listening to music and cannot hear you,' to deter him from chatting shit about the crap he is watching.
And OMG, when we are watching something together, that he has already watched, he does my head in with 'oooh you will like this bit,' and 'listen to this coming up now' and 'you're never gonna guess what HE says in a minute!' Drives me mad!
Someone narrating what they're watching, and chatting shit about it when YOU are trying to concentrate on something else is infuriating.
