One of my favorite things to do on a hot day is sit in the fountain at Washington Square Park.
No, not really sit in the fountain. It's almost like an amphitheater, with steps going down to the water. I usually sit on the steps between two sprinklers, with people I don't know, some alone, some in pairs, some in big groups, some reading, some chatting, some just tilting their faces up to the sun.
My favorite moment is when the wind hits the fountain just the right way, and droplets of cold water spray all of us sitting on the fountain steps. Even though we're all strangers, in that second we all gasp, laugh, and look at each other. There's something about it that's just... comforting.
