Dreams
"You have to concentrate on Occlumency, Harry. If Professor Dumbledore didn't think it was important then he wouldn't have asked Professor Snape to give you lessons."
"C'mon Hermione, give the guy a break. If I was stuck in a classroom with the greasy git every evening, I don't think I'd be up to much either."
"Honestly Ronald! It's not every night, and I'm sure Professor Snape knows what he's doing. Harry would tell me if he didn't think he could handle it."
Ron rolled his eyes at Harry, as if to share a 'mental, I'm telling you.'
Harry didn't mention that the reason he wasn't practising was because he didn't want to miss a single dream. They were the only place he could tell Hermione he loved her.
