"Will I? I look forward to it, though I really shouldn't be saying that out loud for another year," It was obvious that the most difficult thing to getting around Peter's thought process was going to be the morality of the situation with regards to student/teacher. The age thing didn't bother him nearly that much, but this? This could lose him his job and he realized that he was going to be pushing the limits.
Granted, if he didn't work at Hogwarts, would it be the end of the world? He could sell potions really, on his own, and be damned good at it. Shaking his head of the thought, he quickly looked back to her and then smirked some, "Only fifteen minutes? You poor kids and your summer jobs. I won't be around here in three hours, but I'll be at my place. It's near here."
Did he just invite her over? No, not quite. Or that's what he told himself. He was just being nice, and saying he could be available to walk her home, "Though, I'm sure your father wouldn't be entirely pleased seeing me walk you home at the end of the day after the conversation we've had."
