Sometime you start to desperately look for your car keys before realizing that you are in fact driving right now and the keys are in the ignition

Same thing always happens to me, but with my bed pillow. I'll wake up groggily and wonder where my pillow has went before realizing that I am in fact driving right now.

My car doesn't need the key to be in the ignition, just in the car. So when I look for my keys, I really don't know where they are.

Or in your hand!
