I thought I lost my phone today... I looked rather silly when I found it on the coffee table... approximately 1 minute and 36 seconds later... *cough*

Don't Panic
Just chill, and you will be sweet. And you won't look like a douche upon finding.

Look EVERYWHERE!
Not just where you think is the "right" spot.
I mean EVERYWHERE.
Your memory is not good at this moment in time.

Breathe
This helps for the whole calming/living situation.

... and by this point you should find what you are searching for!
