Few days ago I was invited by a friend to help prepare for the festival.
数日前、私は祭りの準備を手伝いを友人から誘われました。
That was three days before the day.
それは当日の三日前でした。
So my role was a chore of the day.
だから私の役割は当日の雑用でした。
However, I was very happy because I was the first time to participate in the preparation of the festival.
しかし、私はお祭りの準備に初めて参加したのでとても嬉しかったです。
