"You don't know Bach?" Sometimes, Justin couldn't comprehend how purebloods got on at all. "Listen to this; it will change your life. I can play it on my cello, but it's far from sounding anything like Bach's performance. I would like to learn Bach's six suites, but I've barely mastered three." Justin was rambling, and he was well aware; he just always had a tendency to not shut up, when he was discussing something he was passionate about. Something he was sure Sally understood.
"Sorry about that." He gave a small laugh, and turned the music down, as he moved on to her next question. "Yes. I know it's probably not a good idea. But, after everything - I just thought screw it, you know? If i'm going to be sent owls with exploding jars, may as well live my life to the fullest while I still can." He took a breath, as he turned the car back out to the muggle side of town. "Envious? You don't need to be envious, Sally. Someone as intelligent and ambitious as yourself, will work out what you want to do and accomplish it. I'm sure."
