"Don't put that up, it's sure to be infested with nargles!"
"It's just mistletoe, it's a tradition and don't let mum hear you talking about nargles again."
"You always take her side, sometimes I think you don't even believe half the things I say!"
"Well if there had ever been a sighting of a nargles or a snorkack outside of the staff of the Quibbler it might be easier!"
"Ahem. Ladies."
Ginny wheeled to look at her brother George, face almost as red as her hair to have been caught bickering like a child.
"It's not… uh… Hi George."
"Morning Gin, Luna. If I might make a suggestion, before you wake the whole Burrow. What about a nargle catcher?"
"A nargle catcher? Um, George, what-?"
"Ohh, how lovely, I think I have some dirigible plums left over. Do you have any butterbeer corks?"
"I think you will find that in a house of 6 males there will never be a shortage of butterbeer corks, dear Luna."
Ginny watched, mouth open in amazement as her brother and her lover fashioned a rather ersatz lamp cover from cork and radishes, then charmed it to be transparent. Soon the offending sprig of mistletoe was suspended from the ceiling and covered by the homemade nargle trap.
"Lovely, now the nargles won't attach themselves to your beautiful hair Ginny." breathed the blonde witch. She gazed adoringly at the hair in question "It would be a shame to mar your natural colour with dirigible plum juice."
Ginny Weasley giggled at her loopy loony Luna. How could she ever be cross at such a silly, adorable thing?
"Merry Christmas, my love."
