"I haven't bothered with the glasses. I don't think anyone here would be fooled by glasses," he said chuckling. "I actually got the idea from Hermione. She fixed her teeth, so eventually I decided that I could fix my eyesight."
Harry shrugged. "There will always be people like that. I don't think it has to do with bloodlines. Even Muggles are like that." Human nature was the same regardless of decades or powers as far as he'd seen. "The Muggle world is pretty awesome when it comes to technology, but it's still not magic. There's something special about being able to cast spells." He shook his head. "Oh no, the Statute of Secrecy has been enforced very heavily. You cast magic in front of Muggles, you end up in Azkaban. That hasn't changed. I think in a way Muggle technology has done what the purebloods wanted to do, create a bigger divide between wizards and Muggles because it was just too dangerous. I just know because I lived in London and I would dress as a muggle, walk around, get to know what was happening there."
He smiled again. "I know you did, and we've seen that devastation too. Maybe even worse. In 1997, he took over the Ministry. He was in charge for a whole year and people just let him." He didn't say that her engagement probably set Snape on the path he chose. That was something between the two of them. "His love for the Dark Arts kept me alive. Draco is pretty good with the Dark Arts too. I've cast the Unforgivables and so has almost everyone I know. I've learned that it's not whether you know them and cast them that's the problem, it's why you use them."
