TIFU by hanging a heavy painting with two nails

I moved into a sketchy apartment in NY a few yrs ago. The bedroom was on the 2nd floor so that’s where I spent most of my time. One day, while I was on my computer, i heard a loud crash and thumping from downstairs. The stairwell lights flicked on. It sounded like someone was coming up the stairs. I instantly accepted that i was either about to die or get kidnapped.

Turns out, one of the two nails I used to hang a heavy painting gave out, causing the painting to swing downward and flip the stairwell light-switch on, and kept scraping against the wall as it swing back and forth. It made the noise of heavy footsteps coming up a staircase. Pretty sure it took a few minutes off my life.

In the same week, my shower mirror fell and hit the tub with a loud ‘bang’ at like 3am. The bathroom was right next to my bedroom. In my panic I managed to let out what was probably the least intimidating and shrill voice imaginable, i yelled “wtf do you want” into the darkness.

TL;DR i thought someone broke into my house because i tend to mount things improperly
