Out for a walk the other day, the super-reflective wall of my neighborhood's "sports pavillion" caught my eye. It is almost a mirror, albeit one that needs a good cleaning. While I don't think I would ever post a phone selfie that provides that close-up of one's face at a funky angle, I don't mind the occasional odd reflective portrait.
These reflective windows are actually the walls of the huge indoor swimming pool. From the inside it is a clear view out. I bet the swimmers wondered what the heck I was taking a photo of!
