Some years ago my wife and her sister took their mother shopping. One of the things on the list was a new bra for the mother in law. Anyway the expedition was made, the bra was bought and fitted and the old one dumped in the backseat of the car.
There the bra lay in full view of anyone looking in the window. Of course I drove around and parked up for quite sometime without spotting the aforementioned garment. It finally came to light when I was in the local builder provider's yard and I went to fold down the seats. Enough said.
