Sometimes I have to hurry and put things away because someone is coming over, so I shove everything into a basket of all kinds of unrelated things, and then I forget I've done that and crazily look everywhere except the junk basket for the "lost" object. Now I've learned, look in the baskets first.

Usually, when you cease to think about it you either come across it or recall where you put it.

probably got discarded with some peelings awhile ago. how much is your time worth to look/be frustrated when you could simply add it to your shoping list?

They say that if you call out its name repeatedly, "knife sharpener" it helps some people to remember where they put things. It never worked for me, but some people swear that it works for them.
