My father is a serial offender at Not Turning Things Off. Lights, lamps, computers, ipads, TV, music etc. This evening he's come through to the lounge and has been sat for half an hour watching the football whilst his music (which he can't be arsed to turn off) has carried on playing in the study. And he turned off the programme my DM and I were watching as well so he could watch the football.
I get up to pause it (for about the 3rd time today) and he shouts at me like I'm 6
. I wouldn't mind so much, but I'm the mug he rings up whenever anything breaks and gets to fix it because he doesn't look after any of his stuff. Last month it was a burnt screen on one of his laptops after he put it in his bag without turning it off properly and it overheated (yes, that could have been much worse than just a burnt screen. My parents are very lucky it wasn't.)
So AIBU to think you don't leave music playing for half an hour whilst you're watching TV??
It's not like he was nipping to the toilet or grabbing a drink.
