Then he smiled.
"Water flows downhill."
I thought he was joking.
"Sure," I said. "But it never did that before."
He shrugged.
"Maybe you've just never noticed."
That was the beginning.
At first, I didn't consider it a dispute.
I considered it a problem between neighbors.
Problems between neighbors should be solved by neighbors.
So I took pictures.
I sent Trevor a message the next morning.
Hey, I took a few photos from last night. The water seems to be concentrated along the new drainage area behind your patio. Maybe we should take a look together.
He responded several hours later.
Probably just a bad storm.
I looked at the message.
Then at the photographs.
Then back at the message.
I decided to let it go.
The second storm came eight days later.
Same two streams.
Same part of the fence.
Same muddy pool.
This time, Rachel recorded video.
When I showed Trevor, he barely looked.
"We had professionals do the work," he said.
"I know."
"So everything was done correctly."
"Then why is the water coming into my yard?"
He sighed.
"Daniel, I can't control rain."
I almost said something angry.
Instead, I walked away.
I wish I had understood then that some people mistake patience for weakness.
The third storm damaged the bottom of the fence.
The fourth killed several hostas.
The fifth turned the back corner of our yard into a swamp.
By then, mosquitoes were appearing after every storm.
Cooper refused to walk near the fence.
Rachel stopped planting anything there.
And I started checking the weather before making plans.
That was when I realized something important.
This wasn't just water anymore.
It was becoming our life.
And Trevor didn't seem to care.
In fact, he seemed to enjoy the fact that his patio remained perfectly dry while ours turned into mud.
Three years later, I would understand why.
But at the time, all I knew was that something had changed behind our fence.
And the man who caused it had no intention of fixing it.
The first year, I tried being reasonable.
The second year, I tried being official.
The third year, I stopped asking.
That distinction would eventually matter.
After the first few storms, I contacted the neighborhood association.
Our HOA president was a woman named Patricia Coleman.
Patricia was not a bad person.
That was almost the problem.
She believed every disagreement could be solved by putting two people in the same room and asking them to "find common ground."
She came to our house one afternoon with a clipboard.
Trevor came too.
I showed Patricia the photographs.
I showed her the video.
I showed her the damaged fence.
Trevor stood beside her with his arms folded.
"Daniel is upset because his yard gets wet," he said.
"My yard didn't get wet like this before your renovation."
"You can't prove that."
I pulled out a folder.
"I have photographs from previous storms."
Trevor laughed.
Patricia looked uncomfortable.
"Let's keep this constructive."
I pointed toward the fence.
"The water comes through at exactly two points."
Trevor shrugged.
"Gravity."
Patricia nodded.
I stared at her.
"Gravity?"
"Well," she said carefully, "water does naturally move downhill."
"Yes. But someone changed the slope."
Trevor immediately answered.
"I improved my property."
"And my property became the drainage system."
He shook his head.
"That's not what happened."
Patricia eventually recommended that we each speak to our own landscapers.
That was the end of the meeting.
Nothing changed.
In fact, things became worse.
Trevor installed a small retaining wall.
Then another section of landscaping.
Then a shed.
Every project changed the way water moved.
The streams coming under the fence became stronger.
One afternoon after a storm, I found several inches of muddy water around the maple.
Rachel was furious.
"This isn't normal."
"I know."
"Then do something."
"I am."
"No, Daniel. You're documenting it."
She was right.
I had become the historian of a problem nobody wanted to solve.
I had folders named by month.
Photos.
Videos.
Rainfall records.
Screenshots of text messages.
Emails.
Receipts for damaged plants.
A fence repair invoice.
Even a veterinary bill after Cooper developed an infection from standing water.
Trevor's responses were always variations of the same thing.
Rain happens.
Talk to your landscaper.
My contractor says everything is fine.
Not my responsibility.
Once he sent me a laughing emoji.
I stared at it for several seconds.
