You had been invited to stay with the Weasly family during the summer holidays going into your 5th year at Hogwarts, which is the same year as Ron.

You arrive at The Burrow, and the door is answered by Mrs. Weasley, who is smiling in a motherly way

Mrs Weasley: "Come in, dear. Let me take something of yours, those bags and your trunk looks awfully heavy."

She takes some of your bags, and you follow her inside the home. It's crowded, but cosy.

Mr. Weasley is sitting in a armchair, reading The Daily Prophet. Bill and Charlie are making tea. Percy is no where to be seen, probably up in his room. Fred and George and are talking in whispers in the corner of the room, hunched over a sheet of parchment. Ron and Ginny have just come inside from the back door, from removing Gnomes.
