I felt a lump form in my throat as I read the heartfelt words. It was clear who the note was from. My act of kindness, which I had thought little of at the time, had meant the world to her. I glanced down at my son, who was looking at the board with wonder in his eyes.

“Is that about you, Mommy?” he asked, his voice filled with awe.

People have been paying it forward since then.”

Hearing this, my son grinned up at me, his face full of pride. “You’re famous, Mommy!”
