You see, I also have a bad memory. I think there was this one time when I was little, and my childhood friend and I were sitting under a big tree in the middle of a meadow. If I remember correctly, there was a breeze blowing, making the grass ripple like gentle waves. I kinda remember that we promised something to each other, but I can't remember what, exactly. Oh well, it's not like people usually remember these kinds of things, right?
