Question

whenever curtis glanced in brigids direction, she shook her head in disapproval. he was dishonoring his ancestors by being irresponsible with his powers. he was supposed to keep his gifts hidden from others, but there he was, spilling his secrets with every sparking snap of his fingers.

not wanting curtis to ruin her day, brigid closed her eyes and inhaled deeply, releasing the tension that clawed at her shoulders.

\that boy is breaking all the rules,\ nadia texted brigid.
\true, but its rude to be staring at your phone during a block party,\ brigid texted back.

just then, curtis flicked his fingers in a way that shot sparks onto a nearby shrub. dry from the lack of rain that summer, the shrub lit up like a match. brigid watched as people backed away from the scene and someone shouted to call for help. though small now, she knew the fire could become a monster if it got out of control.
