"But why can't I?! She doesn't even like you! You can barely get her to eat every once in a while!"
"Because I'm older and I've graduated, Aberforth. You can't give up school at your age", he said, trying desperately to keep a serene face.
"See, that's where you're wrong.
"Mr. Headboy Prefect winner of every prize ever existed at Hogwarts, he can't give up his education. But useless goat-herding Aberforth's an entirely different situation – "
"You are not a situation, Aberforth." His face remained impassive. "You have not come of age, I am responsible for you, and I am telling you, you will go back to school when the summer ends."
"I hate you! She hates you! Why can't you leave us alone and go save the world or something?!" He picked up a jar of jam from the table and hurled it in his brother's direction.
Albus waved his wand and the flying jar dissolved into grains of sand. He closed his eyes as they came smashing to his face. Aberforth's face turned several colors at once.
"I HATE YOU!"
He turned away and left the house, smashing the kitchen door so that one of the glass panes fell off and shattered against the floor. Somewhere deeper inside the house, there was a mild explosion.
Ariana walked into the kitchen holding a white blanket, her bright blue eyes looking as if she couldn't open them wider. Albus went to her and gave her a hug.
