Ok. But I still don't get it. I wrote, "The paper in fact is not the song. It becomes a song when it is sang. When it is given voice. In fact it is hard to say what the song is. You can play it with different instruments. You can play it in its recorded form on various media. All these will sound different. I was thinking "reality" is like this too. So I don't think the sign can make the airport."

How is this related to a meme?
