Stop. Breathe. Think. Recheck everywhere. Car, wallet, pockets, any bag, anything. My mom once did similar, started to panic and it was right there. Hope its the same situation!
Found it!!!! Of all the odd ball places I don't even remember setting it there!!! I have never in my life put money by the TV I had about given up and went to change the channel and was like "OH!!!"
I did that once, but it was with a $100 bill. Got to work and realized I couldn't find the stupid thing (I had put it in my back pocket of my jeans). Figured it was gone.. was SO mad at myself.
I got home a couple hours later and there it was, sitting in my driveway! I couldn't believe it hadn't blown away and/or been found and picked up by someone!
