Q nods agreement, glad that Lucius isn't offended. Uh oh! "Er, yes," Q says, mentally cursing himself. "In a rather roundabout way." He clears his throat noisily, hoping he won't have to explain further.
"Thank you," Q smiles, pleased. "Really?!" His eyes light up. "Oh! I'd like that very much! Thank you!" He tells himself not to gush, but it's not easy. "I'll try not to make a nuisance of myself Mr Malfoy. Your piano-forte is much nicer than my own piano! Er," he hesitates to mention this. "If you'd like, I mean, if you were interested, I could give you lessons. Sort of as compensation? Take up from where you left off?"
