I lost a puzzle piece
I spent the better part of a month putting this stupid thing together and right when I was at the 90% mark, I accidentally flipped a piece behind the dryer that I was building it on. Why on the dryer? Because I have 5 cats and do not own a “puzzle box” that would let me have an incomplete puzzle just laying about my house. I pulled out the dryer, the cabinet between the dryer and the washer, the washer, disconnected everything and put everything back. I even used a damn Ryobi inspection camera to look inside the dryer and under the unfinished wall that the dryer is up against.
Never found the piece and now a part of my life will never be complete.
