ginny’s laughter comes in bubbles, prolonged just the right amount and always ending with a joke of her own. her eyes glow and flicker and crinkle and her lips stay in an upturned spot, enticing another joke to bring back the laughs. and, when it comes, she throws her head back and lets out a sound of sunshine and genuineness and something so infectious it leaves the room ablaze and grinning.
luna’s laughter is uncontrollable, starting and staying and ending at the same level. she doesn’t mind people seeing her shake with the glee or swing her feet as she recalls the initial joke so fondly it makes her toes dance in their mismatched shoes. she always comments on how funny what happened was and stays laughing for minutes after everyone else has stopped.
harry’s laughter is contained, small and bumbling and awkward but endlessly happy. he’s grown accustomed to the security that has surrounded him since he first arrived at hogwarts, yet still keeps his voice quiet, hesitant to draw more attention to himself. he doesn’t mind much because, as he watches his friends laugh with him and around him, it keeps the smile on his face longer than anyone else.
ron’s laughter is loud, fits and bursts that leave his stomach aching and his cheeks sore. he laughs so hard he snorts, causing him to laugh harder until he has tears in his eyes and he’s banging his hands on a desk or smacking his legs or joyously hitting anyone near him (mainly harry, who swats ron’s hands away with a brotherly irritation and affection). his laughter alone lights rooms and makes passersby stifle chuckles as he doubles over and catches his breath.
hermione’s laughter is shy, short giggles and breathy smiles that she can’t keep hidden no matter how hard she tries. she always looks down, shakes her head, appreciates the humor no matter how begrudging her acceptance of the chaotic flow of giggles is. when she laughs, it leaves everyone around her feeling mystified and accomplished and important. it leaves her feeling grateful and light and whole.
