把这一句，留给此刻的你
I originally had an idea about a family of people who were homeless, just traveling around without any solid roots or any home, who made their way around working wherever they could. I started it with them. The idea of Joe as a protagonist came along a little later.
我最初想到的是一个无家可归的家庭，他们四处流浪，没有坚实的根基，也没有家，他们在任何可能的地方工作。我和他们一起开始的。乔作为主角的想法是后来才出现的。
