I don't remember ever forgetting where I hid something; I have several plastic tubs in my laundry/craft/wrapping area of the basement, and gifts go there as they accumulate. By the time I set up this system both DDs were past the searching stage - as in not living here anymore. I don't remember what I did in earlier years. I'm pretty old, too, Joyce. BUT - just yesterday I bought a gift card for my son-in-law. I KNOW I had it in my hand when I emptied the shopping bags. I've searched every room in the house, including those bags and the waste baskets, as well as my puree and the car. It's nowhere to be found. I think I'll just buy another card. The original is bound to show up sometime (March, maybe?), and we'll use it ourselves. Growing old beats the alternative, but I really don't like the memory gaps that just spring up. I can't find what's supposed to be in those holes!
I feel your pain. The craziest thing I have lost is two "garters". I don't even know if that's what they call them. I am so short that I use them to push up sleeves that are too long for me now. I acquired these about a year ago from a jewelry party, and have misplaced them somewhere in my apartment. I have searched every inch of the place and cannot find them. It is very frustrating.
