Two things I like about this post, one of which I’ve already mentioned.
The second is the puntastic title. By donating liquid to the parched earth, you’re part of the solution to the problem of drought. Yes
But you’re also part of the solution because the expelled efflux consists of soluble substances that were, literally, a part of you.
Solve. Solvent. Solution.
Sol (the sun)? Solitario? Solomon?
(no dictionary at hand to tell either way)
