The sun felt especially warm on David’s skin as he strolled through the park, his chest swelling with pleasure. The air was filled with the scent of blooming flowers, and he inhaled deeply, savoring the moment. He had been looking forward to this for ages. He checked the time, eager for the evening to begin.

He unlocked his phone, anticipation bubbling inside him. A new message. It was from Mark, the host. David's eyes fell, scanning the text.

"Hey everyone, major problem. We are going to have to cancel the party. Really sorry."

The flowers seemed to lose their color. The warmth of the sun felt less intense. David slowly lowered himself onto a park bench, the joy evaporating.
