It's best to never cry over spilled milk, because it may just be in your favor.
Last week I was opening up the closet door in a room that has been turned into our walk-in closet. Now, above each closet door there is a hanging display of all of our hats. There (was) also a shelf that I sheepishly put up (wasn't sure it'd stay in place) in January, below the hats, holding our watches and small bottle fragrances.
It'd been adhering to the wall nicely for months with no issue, but this particular day, I opened the closet door, a hat popped off its display bracket, knocked over not only a watch or two, but the whole shelf came crashing down. Whomp. Whomp.
Luckily, all perfume bottles were intact. There's a small puncture in one of my watches, yet nothing so bad that I'd need to stop wearing it. The shelf was also intact, but I knew I hadn't any interest in attempting to adhere it to the wall again, so hello!
