Unhappy people hate the rain, fear it, run at the disdain of being wet.
They have become too dependant on the sunshine for happiness.
Heavy saturated clothes is a metaphor for the discomfort they hold in their heart.

Happy people bask in the rain, dance it, are renewed by it.
They know that the darkness wont last,
A few moments of shade, for days and days of rays, is a fair trade.
When it rises, when it sets, They appreciate it for what it is.

Beautiful; but temporary.
