Beautiful Feet?

What constitutes beautiful feet? I have come to ponder that question today and cannot come up with an answer. I went to Staples today to get some supplies. As I was leaving, there was a male employee sitting by the exit door. I noticed he started to point down toward the floor. I thought he was indicating to me that the floor might be wet and to be careful. Afterall, Ernesto is dumping some rain in the area. I guess I gave him a puzzled look and he said, "You have beautiful feet." What kind of response do you give to that? I was puzzled. So, I said thank you and walked out chuckling about it.
