It started when people stopped bathing
Or showering.

Every day before they went to work or after their 5 mile run.  People just stopped stepping into their tubs
Or showers
To turn the faucet handles that activated
Cold and hot water to fall from the plumbing.

They gradually
Lost interest in hygiene. Personal cleanliness was ghosted.

Everything else mattered to them,  until it didn't.  Getting their kids to school on time mattered, finishing the work project by deadline mattered, visiting relatives in Montana mattered, driving to the store for groceries mattered, until it didn't. Simply ceasing soap and water on flesh.

They just stopped bathing. It's not that they were afraid of water. If near the ocean they would still run and swim in the waves,
Or jump into the pool at the Hilton. No they weren't afraid of water.
It was something else
So slow
And insidious that it was hardly noticed at first.

The domesticated animals picked up on the phenomena first.
They became anxious. They scurried, tried vocalizing. They sensed a lack of intention from their care givers. They sensed a lack of worthiness inside of their humans. The animals began to wonder about their own well being.
What was their future?

Once you start with a variation from normal,  from routine,  from tradition,  the pendulum swings.
The people didn't realize what was happening. Then it slowly dawned on them over time.
They didn't feel needed.
But kept it a secret. The secret necrosed from the inside
Out. They forgot that connecting to one another
Was vital to survival. Their silence could be deadly.
