A man was sitting in a cafe and received a letter without signature or address. He did not take it apart, but just sat in the same position every day, looking out the window at a foggy blue tile on the roof of the art museum. He wasn't sure what he was waiting for—the content of the letter, or the moment when he was ready to respond. It's rainy in the south, and the color of the roof will change with the weather, but he found that even if the roof was repainted and the color changed, he would still look up at it. About waiting, about responding, about how a person can confirm whether he is still in the same place through an unchanging scenery.
Intention: Waiting is not about passively staying where you are, but actively approaching the moment when you are ready to respond.
