My kitchen drawer had three butter knives permanently bent from that exact move.

My old house had a corner seam in the living room that cracked every single winter for five years straight. The guy who flipped it clearly rushed the drywall, and we paid for it with constant spackle and touch-up paint. Calling it dishonest is so true, because it's a hidden problem you're passing on to someone else. That kind of work never actually saves time, it just moves the hassle down the line. It's like a bad debt that eventually comes due.

Read a great article about how they're designed to keep you hooked.

Mentioning the vitamin C serum trend is a good point, @the_parker. That was a mess. But mixing acids from separate bottles is worse. It's not like cooking where you can just add a pinch of this and that. A glycolic peel and a salicylic peel are each buffered to a specific, stable pH. Pouring them together in a bowl completely wrecks that balance. You have no idea what the final pH is. That's exactly how you give someone a chemical burn instead of a treatment. It's lazy and dangerous, not creative.

Just be super gentle with the curtain, maybe a dry brush first.
