Sounds like my mother, except for it being a computer rather than a tv. She seriously threatened to throw out her computer because "it keeps putting things in Italics, and then the next sentence is not in Italics". Yes, you and I know how easy it is to press Control and i for Italics, but I have given up trying to explain it to her, as she does not hear what I say. She also thinks that I cannot know anything at all ever about computers, because I have not been a computer programmer all my working life.
She has poor eyesight so the mouse is set to move slowly and leave a "trail". The double click speed has been slowed down, and the icons are very large. When anyone else uses her puter they tell her it works slowly, and then she tells me she needs a new one. She was determined to get two screens so that she could cut and paste.

Allegedly my nephew uses two screens, but that is because he works in IT. I said she should not spend the thick end of £2,000 on a new computer just to get two screens, because that estimate did not include the screens or the software needed to link them together, or the labour for someone to set it up. From this you might think she uses the puter a lot, no, she just sends and receives about four emails a week.
and breathe......
