When my 12-year-old son Ben took up our wealthy neighbor’s offer to shovel snow for $10 a day, he couldn’t wait to buy gifts for the family. But when that man refused to pay, calling it a “lesson about contracts,” Ben was heartbroken. That’s when I decided to teach him a lesson he’d never forget.

I’d always known my son Ben had a bigger heart than the world seemed to deserve. He was only 12 but carried a determination that could humble men twice his age.

Even so, I never imagined I’d be standing in the icy driveway next to my husband, exacting revenge against the man who thought cheating a child was just another business move.

It all began on a snowy morning early in December. Ben was buzzing with excitement after shoveling the driveway while I made breakfast. He burst into the kitchen, cheeks flushed from the cold.

“Mom, Mr. Dickinson said he’ll pay me $10 every time I shovel his driveway!” His grin stretched ear to ear.

Mr. Dickinson, our neighbor, was as insufferable as he was wealthy. He always bragged about his business ventures and showed off his luxury toys.

It wasn’t hard to guess he thought he was doing us all a favor by letting Ben “earn” his money. Still, Ben’s excitement was contagious, and I wasn’t about to crush his enthusiasm.”That’s wonderful, sweetheart,” I said, ruffling his hair. “What’s the plan for all this cash?”

“I’m buying you a scarf,” he said with the seriousness only a 12-year-old could muster. “And a dollhouse for Annie.”

His eyes sparkled as he described every detail of the red scarf with tiny snowflakes, and the dollhouse with working lights that Annie had been obsessed with since she saw it in the toy store’s window display.
