The answer to the riddle was Drooble’s Best Blowing Gum wrappers.
You might not be impressed,
Obviously, gum wrappers aren’t usually impressive. Most people consider them trash.
But we assure you, we’re from the best.
They’re the wrappers from Drooble’s Best Blowing Gum, and they’re given to Neville by his mum—once one of the best Aurors.
We are legion; year after year,
By nobody are we held dear.
Nobody holds trash dear. But Neville, who introduced himself to Luna as “Nobody” does hold them dear, and Harry thinks he must have enough to cover the walls of his room.
It is our usual chore
To keep sweetness fresh inside,
The wrapper keeps gum fresh.
But we have done something more;
We might have made you cry.
Well, the scene in St. Mungo’s certainly made me cry!
And a new riddle. This one is another ship.
When it becomes too much to fight,
He brings to her all of his might.
When it becomes too much to bear,
She brings to him the bane of despair.
Must go to bed…I have to get up at 5:30 tomorrow morning. *sigh*
