Life is like living in both Heaven and Hell.
Some days you don't want to get out of bed, because it's too damn comfortable. And plus you really can't be bothered to face the World.
Some days you can't wait until you're outside, where you can be free and open.
And then some days you get out of bed in such a mood, and have the ups and downs.
I guess each day is different, but that's the point. What would be the point in living, if every day was the same? Bad things are just there to make a change to the good, to make a balance. Without that balance we'd all be bored of life.
