Luna was sorry to see Ginny go. Her lap was getting cold now, what could she do to keep it warm. Settling the chair down now that her friend was gone, she received her wand with a smile.
"Thank you. I was afraid it had fallen into the batter of the cake earlier."
Mister Lovegood took a seat as well, and began to sing Happy Birthday to Luna in a variety of languages. He did it this way because he wanted all the faeries that lived in the magical kingdom under their house to know that it was Luna's birthday. He just hadn't discovered what language they spoke yet, as they had yet to answer his attempts at communicating with them. Luna joined in the song too, though she only sang in English. Instead of saying her name, she always said Ginny's name in verse. She thought it would be bad luck to sing her own birthday song.
"Now blow out the candles, child!" Mister Lovegood exclaimed.
Raising her wand, Luna casted a spell to summon a gust of wind. It flew about the room, extinguishing the flames of the candle before launching itself under the table. It flew right up Ginny's skirt where it stopped, causing the skirt to billow and expand.
