I did it myself the other day. I wasn't quite ready to be inside, so I got a snack and sat. The crinkly sound of my wrapper soon drew a new friend.
I laid back and enjoyed the sunshine, the quiet clatter of people, the construction worker who lighted the sound of his occasional hammering by singing "DAY-OH!"
Of course, being one of the most popular squares means it won't stay still for long. In fact, I walked by the very next day only to find that the square had been transformed once again to show free movies through the weekend.
