Tommy held the key up to the sunlight, watching it glint and sparkle. His grandmother's words echoed in his mind: "This is a magic key. It will only work if you use magic words." Excited by the prospect of unlocking hidden treasures, he began to imagine all the things he could discover.

"Why won't it work?" Tommy muttered to himself, trying the key on a locked drawer in vain. His grandmother, sitting nearby with her knitting, looked over with a knowing smile. "Remember, Tommy, magic words are ‘please,’ ‘thank you,’ ‘excuse me,’ and ‘sorry.’ Try using them!"

"Can I please borrow your ball?" Tommy asked, watching in amazement as the key sparkled in his hand. His friend nodded with a grin, and Tommy felt a warmth spread through him that was as bright as the key's glow.

"Thank you for the cookie, Grandma," Tommy said, noticing how the key glowed even brighter. His grandmother nodded approvingly, "See, Tommy? The real magic is in the kindness and respect you show to others."

As Tommy held the door open for his classmates, he realized that the smiles and thank yous he received were the true treasures. The key in his pocket twinkled, a constant reminder of the power of good manners.

He knew now that the key's magic wasn't in unlocking things, but in opening hearts. "I'll always use my magic words," he promised himself, feeling the happiness and friendship they brought into his life.
