When Severus talks like this, you should listen, and Q does, wide-eyed. "Of course Severus," he agrees instantly. "I'll sketch and I'll even tie my right hand behind my back. But", he takes a deep breath. "I'd like to have you come and hear me play The Art of Fugue by Bach, the best example of contrapuntal composition ever done. Just so you can see where I might need work," he adds, flushing just a bit.
"Oh." Q looks glumly at the damp, sticky mess on the table. Not much point in trying to put them back together. "Are there any more?" he asks with a sigh.
