Professor Lupin's hands glides on the desk in front of him in an absent-minded manner while he explains something to the class. Harry wouldn't be able to tell what the lesson is about, though, despite the fact that the professor is standing in front of him, because he's too distracted by that hand.
The professor has beautiful hands, Harry thinks, they are a little wrinkled, which is part of their beauty, and the way he moves them is extremely graceful.
"You seem distracted, Harry," says suddenly professor Lupin, startling him.
"You have my full attention, sir," is Harry's honest reply.
