Mia turned and smiled at her friend. "It's more to do with the International Statute
of Secrecy thing than it is the Underage Magic thing. The Ministry isn't tracking specific
wands or wizards but the presence of magic in general. When a Muggle-born is at home,
there's a higher chance of random Muggles that aren't aware of magic stumbling upon the
secret if children are just randomly twirling their wands about. However, in magical
households, magic is constantly flowing, and the ministry likely leaves it up to the parents
to make sure the children aren't using their wands outside of Hogwarts."
Lily's mouth had dropped open in shock, but before she had a chance to ask more
questions or to retort about unfairness to Muggle-borns, Sirius turned the radio up,
drowning out her protests.
"Please, swallow your pride... If I have things you need to borrow.. ."
Sirius scoffed. "Swallow my pride? This reminds you of me? Unlikely, kitten. But
since we're apparently making song dedications.. ." he said with a devious grin, and the
radio glowed purple when the tip of his wand touched it.
"Let's... get it on."
"Absolutely not!" Mia scowled and tapped her wand on the top of the radio, letting
the song change once more.
"Baby, baby, don't get hooked on me.. ."
Mia laughed. "That's better."
"Already on my way there." Sirius grinned darkly down at her and touched the radio
again with his wand.
"Touch me in the morning, and then just walk away."
Mia scowled, folding her arms across her chest. "You're doing this on purpose."
"Am I? Is there a problem, Miss Potter?"
Mia tapped the radio again.
"And they called it puppy love."
She burst into hysterical laughter, loud enough that everyone turned and gaped at
her. Sirius stood by, an amused expression on his face as he tried to understand what exactly
was so bloody funny. Mia continued to chuckle, tipping over and holding her side tightly
until Sirius charmed the song again.
"You'll be the queen of my highway, my motorcycle mama.. ."
Mia rolled her eyes, charming the radio.
