Percy frowned at the comment, not really seeing the problem. "Why do you need to tell them anything? A 'none of your business' should be enough. Or maybe you could remind them that forcing someone is an offence and they could be arrested and considering the state of the Ministry, they'd be sitting in a cell for a long, long time."
He shrugged, not really knowing that to say. "Or you could tell them that you're with someone and it's still none of their business and please go away. Otherwise, just be rude and abrupt, people tend to stop asking questions. It works very well, I must say."
