Once upon a time, there was a little girl named Sophie who loved telling jokes. She had an aunt named Lily who always seemed serious and never laughed. One day, Sophie decided to tell her aunty some funny jokes to make her smile.

Sophie went up to her aunty and said, 'Why don't skeletons fight each other?' Aunty Lily didn't know, so Sophie eagerly answered, 'Because they don't have the guts!' Sophie giggled, hoping it would make her aunty laugh.

Aunty Lily's face softened, but she didn't quite laugh. Sophie tried again, 'Why did the scarecrow win an award?' Aunty Lily looked puzzled, so Sophie continued, 'Because he was outstanding in his field!' Sophie chuckled, hoping aunty would join in.

This time, Aunty Lily managed a small smile. Sophie didn't give up. 'Why don't scientists trust atoms?' Aunty looked curious. Sophie answered, 'Because they make up everything!' Sophie burst into laughter, hoping aunty would finally laugh too.

Aunty Lily couldn't help but giggle a little. She had finally cracked a smile. Sophie felt proud of making her aunty laugh. From that day on, Sophie would tell a new joke to her aunty every day, and they both discovered that laughter makes everyone feel happy.
