The moment Sarah woke up, a silly grin crept onto her face. Everything seemed funnier than usual. She skipped down the stairs, nearly tripping over her own feet, a giggle bubbling up from her throat. Her toast felt like the most delicious thing she had ever tasted.

She caught the bus, and the jostling crowd became a hilarious dance to her. She imagined herself as a super spy, sneaking into the office, the promotion letter in her hand, ready to deliver a comical speech.

At the office, she tapped a pen rhythmically on her desk. She kept finding excuses to wander around, chatting with anyone and everyone, her eyes twinkling. When her competitor, David, walked by, she playfully bopped him on the arm, earning a surprised laugh.
