Inviting Luna to Slughorn's Xmas Party

(...)Luna turned her protuberant eyes upon him in surprise.

'Slughorn's party? With you?'

'Yeah, ' said Harry. 'We're supposed to bring guests, soI thought you might like...I mean...' He was keen to make his intentions perfectly clear. 'I mean, just as friends, you know, But if you don't want to...'

He was already half-hoping that she didn't want to.

'Oh, no, I'd love to go with you as friends!' said Luna, beaming as he had never seen her beam before. 'Nobody's ever asked me to a party before, as a friend! Is that why you dyed your eyebrow, for the party? Should I do mine, too?'
