an ice skating rink
Several people are skating in a skating rink.  Perched above them is a lifeguard on a lifeguard chair.  There's also a safety cone in the middle of the ice
It's unusual to see a lifeguard setup like that unless it's at a beach or pool
What is that lifeguard doing there?
Careful, the water’s hard today. Before we start, would anyone else like some water? I only needed one, but Costco makes you buy a whole case. Of all the things we packed, I didn't think to bring my MetroCard. At one point I had them in a semicircle, but it gave people a sense of equality.
