*sigh* This happens to be on a regular basis! Each time I strongly suspect one of the cats.

And then I go back and look all over, increasingly frantically, until I find whateverit is...and then rememberthat I'd gotten distracted by some silly thing and put it (whatever *it* was) down right there.

'Course, then there's the time that one of the cats really does hide something.

I can't win. But I hope you find your wallet!
