When you suddenly realize you lost something that you just had (ie: eye glasses, keys, cell phone) you get this panic look on your face, your stomach drops and you do a 40 yard sprint to the last location you thought you had them, to realize you had them all along.
Person #1 UH OH! You have your panic face on, what did you lose?
Person #2 I CAN'T FIND MY GLASSES.
Person #1 Get back here dumb ass! There on your face.
