My daughter and I laughed so hard when we read about the case of the missing bun because I did the exact same thing! One minute something is right there and the next minute…POOF! It’s disappeared! I constantly forget where I put stuff as well (and I even tell myself as I’m putting it there..”don’t forget you put this here”-nope still forget)which is annoying and expensive because I end up having to rebuy stuff I already own. I have a “Where the hell did I put it?” Notebook but that only helps if you remember to use it. I annoy myself let alone my husband and kids. Wish I had some advice for you but I’m in the same bun situation you are.
