She arrived at the old warehouse that had been converted into an art space, and the air buzzed with energy. She found her painting. A striking portrait of her grandmother, rendered in bold strokes of color. It was beautiful.

A couple stood in front of it, whispering admiringly. A smile bloomed on Eva's face, wide and genuine. She wanted to hug everyone, to sing, to dance. She felt like all the colors of the world had suddenly become amplified.
