Whisper
"Hermione!" Harry murmured.
"Sh!" She hushed him, not taking her eyes off Professor McGonagall for a second.
"But Hermione-"
"Shush!" She told him harshly.
"Hermy-"
"You know I hate it when you call me that!" Hermione whispered furiously, pressing down so hard on her parchment that her quill nib broke.
"Miss Granger? Is there a problem?" The stern Professor asked, staring down her glasses at a sheepish Hermione.
"No, Professor." Hermione mumbled. An angry blush stained her cheeks as she bowed her head in shame. When the teacher turned away, Hermione turned her head and glared at Harry. "That was entirely your fault! I've never been so-"
"I just wanted to say, you missed out the fifth law of Transfiguration." Harry said, slightly put-out, nodding at her notes.
"Oh, thanks." Hermione went even redder and brushed a curl behind her ear. She hid behind her hair, but even Hermione's mass of bushy tendrils couldn't hide the slight curve to her lips.
