Snape waved the defense off, "I was talking about your little rant about 'trick questions' - which most certainly was whinging, especially given that there was nothing 'trick'y at all about a perfectly reasonable question."
"As for your brother, I have no idea what you're talking about; I've certainly never offered him - or anyone who isn't a Hogwarts professor - rooms in the castle."
"And if you can possibly mistake me for your father," Snape scoffed, "you are blind. And bats."
Snape nodded impatiently as James finally got to the point. "I'm relieved to hear you've been showing some improvement in your wandless casting - and some initiative in training methods when you're on your own. So, by 'precision', you mean your targeting is off? Do you have such problems normally? Difficulty hitting targets with thrown objects?"
