Rain
Rain(it/its) is a fluid of nebulous origin. It is best known for falling on people on their commute to work. The workers revel in rain’s rebellious nature.

Rain exists because of complicated scientific processes which you learned about in high school and probably don’t remember.
The rain cycle
When somebody tells the rain it is beautiful, it gets big and warm and fluffy inside and rises to the sky.
After a while, the rain gets so big and fluffy that it blocks the sun, which the workers sometimes complain about, making the rain feel small and cold and spiky inside and causing it to fall back down to the ground.
While falling, the rain is sometimes complimented again, which causes the rain cycle to restart.
Frequency of rain
The rain is dependent on several random ticks, but on average, the rain cycle restarts every 2000 ticks.
Will the cycle ever end?
Scholars are conflicted on this topic. Some believe that the rain needs workers for the cycle to be fulfilled, whereas others suggest that the rain can sometimes affirm itself without the need for workers’ compliments, allowing it to continue this cycle indefinitely, even after the inevitable extinction of the workers.
Can You drink it?
Scholars are conflicted on this topic. Notable fluid consumers suggest that rain is much harder to drink since normal water usually comes in a cup or from a device which you can put your teeth around. Notable rain enjoyers claim that the difficulty is "the joy of drinking rain", and suggest "catching it in a container if you're a beginner at the hobby".
It should be noted that the rain does enjoy being consumed.
