Don't you think our life is just like a sky?
it can be clear.
it can be cloudy, and dark cloud may come.
it can be rainy or hard rain.
a storm may come.
although rainy, hard rain or storm come, a rainbow will appear,
they bow the rain and bowed to us so we can see the colour of rain bow.
and the sky always be blue,
even at night the sky always blue,...dark blue.
