I said "don't you turn around, wouldn't like what you found out here anyhow..."

Sometimes it's hard to remember that not everyone is the same, and that you can't always find the solution to other people's problems. I think that perhaps the worst is knowing that there is a good chance that there is nothing you can do to make someone happy, because it's not the world that's getting them down, but it's a problem that originates within them (seriously, there is nothing I can personally do about chemical imbalances). It's just rough; it's hard to watch a friend smile, and know that it's only a fleeting sense of happiness.
