“Synesthesia. I have synesthesia.” She pulled her sunglasses away and leaned forward. “You know, the senses thing?”

“No, not really.”

“It happens to some people. Two senses become interlinked. You know, tangled together. Like hearing sounds when you taste certain foods. For instance, when some people associate a sound or color with objects. Like the sound of a voice might be orange? Some people envision numbers in colors, like me. I guess other people hear Mozart when they eat a banana.”

She giggled, and her coal-black eyes softened. “It’s kind of cool. I like to think it lets me see the inside of things. And there are no rules, not really,” she said. “Except infinity. Infinity has no color, of course.”

Her hair was dark and full except for a crescent scar above her left ear where her hair was clean shaven.

Behind them walked two white-haired women. The women stopped and laughed, and then they snapped selfies and then continued to walk and laugh as they looked at the photos.

“I wonder what I would have been like at their age. Just like them, I should hope.”

“What do you mean, would have been like?”

“Come on. I see you glancing at it when you think I’m not looking.”

“I didn’t.”

“It’s a thing.” Her face brightened as she widened her eyes and tilted her head to one side. “Besides, it isn’t real.”

Her hand made a sweep of the city. “It’s too nice a day. And I love it here. You’re a part of everything here. You know, some people believe that’s what happens. The good, the bad…the ugly, the gorgeous. You become part of all of it.”

She threw back her head and closed her eyes and reached up with both arms and wiggled her fingers at a single white cloud, twisting slowly in a tight circle. “This place is as beautiful as the sound of sky.”
