Last December , I received an updated credit card. New expiration date. But since the old one was still good, I set it aside where I couldn't lose it. I lost it.
I knew it was in the house. So it wasn't a matter of someone else finding it. When the old one expired, I went nuts trying to find the new one. You know, searching every coat pocket, looking under every stack of stuff, under the furniture, etc. So I used the number where I didn't need to show the card. Online, for recurring automatic payments, etc.
I found it today! I was making holiday cards and lifted my pack of cardstock in the file cabinet drawer. There it was... I just stared for a moment, but that was exactly the kind of place I would have expected to EVENTUALLY find it.
Isn't it nice to have a year-long mystery solved?
