That's a very pessimistic view, non_existence :blink:
I think happiness does exist, just as depression does - it's just as tangible - but sometimes it can be hard to see things that are wrong with the world when you're happy, and in contrast that's all we can see when we're not happy. Does that make sense? When you're happy you want everyone to be happy too, but you don't want to look at things too closely in case you find out they're not as good as they seem. And then when you're unhappy, you want to be happy, because you would stop feeling like this, but you think you'd have to lie to yourself to get there; or that it's just plain impossible.
Er. What I meant was, I don't think it's that people don't care. It's that...happy people often don't look too closely at things, and a lot of us try to hide how we're feeling. So they just have no idea that anything's going on. Like if you start cutting and wearing long sleeves, and no one questions it for 4 months because they don't expect it from you, even though all the signs have been right there under their noses. People take a lot on faith, you know.
It's only us that don't have any in people.
