Their lips --and, therefore, the rest of their face-- looked so good that I asked each one what brand of lipstick she was wearing. What a surprise to learn that they were all wearing the same one. Given how many red lipsticks exist in the world, what are the chances that each woman was wearing the same? And, yet, they were. Clearly I had to have it. This was too much of a coincidence.
