"Did you see the exhibit?" Marco asked, his voice filled with an irrepressible lightness as he bounced on the balls of his feet. He’d been practically vibrating with energy all morning. He’d barely slept a wink last night. He could scarcely believe it was real.

His friend nodded, "Yeah, it was alright. A bit… abstract." Marco laughed, a genuine, delighted sound that echoed in the quiet cafe. He couldn’t contain his enthusiasm.

"Alright? It was *amazing*! And guess what?" He paused for dramatic effect, eyes sparkling. "My stuff… it's in there! They used my photographs!" The memory of seeing his prints displayed, the way the light hit them… it made his insides feel like they were doing a little celebratory dance. He couldn't stop grinning.
