Ange could only listen to Helena working out the logic. Angelina had never been particularly interested in the logical reason for things, and so she had little to add. Either things worked, or they didn't. Sometimes things happened for a reason, other times they didn't need a reason. If Helena had asked a question about quidditch, Ange could have gone on for days. But twisting words and ideas around to make them more favourable? Not Angelina's forte.
There wasn't much Angelina could do when Helena came at her with the brush. She tried to move out of the way, but her uncontrollable laughter left little room for movement. Paint smeared over her overalls, and Angelina felt tears coming to her eyes. It had been a long time since she'd laughed so hard. Doubling up, Ange had to put her brush down and catch her breath.
"Okay, okay," she struggled to say, "I deserved that." Gasping for air, Angelina continued to giggle but at least now she could speak. Picking up her brush, Ange pressed it to the wall gently. "Merlin, I don't know when I last laughed that hard."
