I'm with Betty on this one. Which reminds me, I need to set aside some money for a little trip to Aerosoles (however you spell it). I love that place. I need some good, comfortable and affordable work/play shoes.
With that said, I love flip flops but I do tend to reserve my wearing of them for around the house in place of slippers and Ocean City or other beachy places. It's all just a natural common sense thing. That's all.
