Where is it?

"Okay, I know where I put it.  It is right here."  Some days I hate those words.  Yes, I like to put things in a certain spot so I can find them when I need it again.  I have gone as far as telling Bob where the item is, so one of us remembers.  We soon found out that doesn"t work either.  Now there are two of us that don't remember where the item is.  Usually weeks go by and all of a sudden the item shows up.  Too young to be Alzheimers.  I chock it up to having a Gremlin in the house that moves things on me.  Do you have Gremlins?.....
