Ok now that you've told the whole PC world, you will find it. (Well, that's how it happens for me.)

I'm sure you're looked everywhere but where it is. And if you became more and more stressed, you might have even looked right at it and didn't see it.

Well, I hope so anyway.... those slick IDs can fly and slide into small areas... clothes, house, car...

Give it one more looksee, mindfully...hopefully you'll find it and avoid the rush tomorrow.
