Nitwit, Blubber, Oddment, Tweak
"Nitwit," Ariana said thoughtfully. The word broke the silence of the otherwise peaceful summer afternoon.
Aberforth looked up from his position lounging on the floor, and grinned. " Blubber".
Glancing at him thoughtfully, Ariana considered the topic. "Oddment".
Aberforth placed his chin on his hands. "Tweak."
"Honestly, Aberforth!"
Aberforth glanced over at his brother. "Nothing wrong with a bit of silliness, is there!"
Albus stood up to release an owl out the window. "You ought to be considering more important things. Someday, I hope you realize there is more to life."
"Someday," muttered Aberforth under his breath, "I hope you do."
