Sarah hummed a cheerful tune as Mr. Henderson from across the street rang her doorbell. She had just finished painting the porch swing a bright, summery yellow. "Hello, Mr. Henderson! What a lovely day, isn’t it?" she chirped.

He looked a little sheepish. "Well, Sarah, I was hoping... I was wondering if you’d consider letting me plant a few tomato plants in your yard. My back isn't what it used to be, and yours gets so much sun."

A warmth spread through Sarah, a feeling like sunshine from the inside. "Oh, absolutely! That sounds delightful! Where were you thinking of putting them?" She was already picturing plump, red tomatoes ripening under the summer sky.
