I went to a surprise party for a friend. One of her friends showed up and I just knew I hadn’t seen her before. She introduced herself, and I recognized her name. Wait a minute! I know you!
We had been swimming together. Neither of us had seen the other in anything but our swim gear. We look very different when we’re dry, not wearing a swim cap and goggles, and we’re wearing real clothes. I had flip flops on, and I suspect she may have been wearing them also, but, otherwise, totally unrecognizable.
