Same thing happened with a park bench near me. It was that ugly brown wood color for years, then one morning it was bright orange. No work crews, no paint cans left behind. Just switched. My neighbor saw it happen around 3am but didn't see anyone doing it. Makes you wonder what else changes when you're not looking.
Whoa, that's creepy. It's like stuff just resets overnight sometimes. I swear my local stop sign was on a different corner last week. Makes you feel like you can't trust your own eyes. What if it's not just benches and signs, but bigger things we just don't notice?
