I have no idea why it is but I can never seem to find my sunglasses when I need them.  I carry a set in the car,  there is one in my office and I have at least three pairs at home.  With the amount of them that I buy I should be buying discount sunglasses.  My eye doctor does not want me to be out in the sun without them. It seems I am always where I took the glasses from last time and did not put them back or else someone else has grabbed mine for an emergency use.
