Rain?

Cold, wet, never stopping.
Always changing, dripping, dropping.

Pittering, pattering, constantly changing,
Splittering,Splattering, never aging.

Slowly at first, then faster, faster.
A mystic spell from an unknown caster.

Here it comes, soothing, flowing.
Down my arms, always going,

Further still towards the floor,
Easing my pain, forevermore.
