We guess that the diary was momentarily given to Ginny for reasons like learning information about the tournament and just because it might have been interesting. So here it is! 

Hi Diary! It's Ginny here. I'm heading off with the rest of the people in the tournament to a classroom! I see Mr. Ollivander, Mrs Quadlina, and Mr. Krum. They're the wand makers! I wonder what they're gonna do! Maybe they'll see if our wands are ready. Bet you seven Knuts!                                                                                                                                                                            

Confession time here's what I've got: 1. I'm using different ink and 2. You owe me seven Knuts! They checked out our wands. The person from Beauxbatons needed a new wand! It was so funny it went like this: "Vere is vy vand." "Very nice. But in bad condition. Vlease pick seven from the selection in the vack." He got a new one but still. Go to a tournament with a good wand dude!
