That Come in did not sound even remotely enthusiastic. It made him feel like turning right around and pretending he had never even come! But he thought Professor Fletcher was likely to be irritated about that and he'd proooobably hunt Lucas down and take 100000000 points from Slytherin for ruining his evening tea or whatever mean Professors did in their free time.

Did come in mean come in? Would he somehow get in trouble? Lucas timidly pushed the door open and peeked inside, licking his lips nervously. He suddenly felt very thirsty. "Uh...go-good day, Professor Fletcher. I've come to talk to you about our...homework. Essay." He patted his backpack. "If you have the time right now, that is. If not, I can come at a more convenient time." His mother's advice was replaying over and over in his head. Be respectful and accommodating. Respectful and accommodating. He could do both of those things fairly well.
