Man, I used to think homeowners just didn't know their own houses. Figured they hired me so they could zone out and let me do my thing. Then I had this one lady in an old duplex who watched me cut into a wall for like ten minutes before mentioning the last guy found a nest of bees in that exact spot. Swear I almost dropped my saw. Now I always ask upfront about anything weird, hidden wires, old pipes, whatever. Learned that lesson the hard way, lol.

My buddy got one of those from his wife a couple years back and he was pissed about it too, same exact reason. He said it felt like the blanket was calling him out, like hey dummy you've been running on fumes for a year and this is all it took. He shoved it in the closet for a month out of spite before he caved and started using it every night. Now he jokes that it's the most expensive thing he owns that he actually touches daily. I get the anger though, because when something simple fixes you it means the problem was real the whole time and you were just white knuckling it. That fake smile at home thing is rough, hope your sister knows she did good even if it stings.
