Sometimes I am so disappointed in humanity. Sometimes I don't believe there is much good left in the world, and I feel discouraged. I hear stories of people doing terrible things to each other, and it's sad.
And then, I see something like this article, and I think how cool people are. How probably, most people are good deep down. I don't know why, but just knowing that somewhere in the world there actually was a house floating on balloons made me happy.
Maybe it will cheer you up, too.
