The engineer stood beside his car, reading the note.
Then he laughed softly.
Three years earlier, an envelope on his windshield might have frightened him.
Now it contained an offer of help.
He placed it carefully inside the car.
Then he drove to the library.
The workshop was busier than usual.
Several students were working on small projects.
One boy had brought a broken portable speaker.
Another was trying to understand why a simple motor circuit kept overheating.
A girl wanted to build a basic alarm that would sound when a door opened.
The engineer moved from table to table.
He asked questions.
He checked connections.
He encouraged students to identify problems before replacing components.
And whenever someone made a mistake, he reminded them that mistakes were information.
Near the end of the session, a young boy approached him carrying an inexpensive wristwatch.
The plastic strap was cracked.
The battery cover was missing.
The watch had stopped.
"Can you fix it?"
The engineer examined it.
"Maybe."
The boy looked disappointed.
"Maybe?"
The engineer smiled.
"That's where most repairs start."
They sat together.
He showed the boy how to inspect the battery contacts.
They discovered corrosion around one connection.
After cleaning and testing the contact appropriately, they installed a replacement battery.
The display flickered.
Then the numbers appeared.
The boy's eyes widened.
"It works!"
The engineer smiled.
"It does."
The boy fastened the watch around his wrist.
Then he looked at the silver watch the engineer wore.
"Yours looks expensive."
The engineer chuckled.
"It was a gift."
"From who?"
"People I worked with."
The boy studied the metal case.
"Was it broken?"
The engineer hesitated.
"Yes."
"Did you fix it?"
"A watchmaker did most of the work."
The boy nodded.
"That's good."
Then he looked down at his own watch.
"Mine's not worth much."
The engineer smiled gently.
"Does it tell you the time?"
"Yes."
"Does it matter to you?"
The boy nodded eagerly.
"My dad gave it to me."
The engineer felt a familiar warmth in his chest.
"Then I'd say it's worth taking care of."
The boy grinned.
He ran back to his friends.
And the engineer remained seated for a moment, looking at the tools on the table.
