She's not broken, she's just a baby
At three years old anything can be amazing and the sparkling colours that brighten the sky are so like magic that she almost can't believe it. She laughs and claps her hands together in joy as she watches the pretty multicoloured lights sparkle out with that loud bang which makes her giggle. So maybe the first one gave her a little fright, it doesn't matter now and all she can think is that every time they celebrate her birthday she wants these pretty lights in the sky.
"Mummy, it's like magic," she declares.
Her mother laughs at the wonder in her eyes and the smile of joy on her little face.
At three years old she doesn't know that magic really exists. She can't see into the future where she goes to a school to learn how to be a witch. She doesn't know that one day she won't find colourful lights against the dark sky so pretty. At this moment she can't imagine the worry, the pain, the fear from seeing different coloured lights shooting out from nowhere. She just really isn't aware that she'll grow up to be Hermione Granger, survivor.
