The invitation sat heavy in Leo’s hand, the glossy paper practically mocking him. He reread the words: “Surprise! You’re turning thirty. Join us for food, drinks, and merriment!” A wave of something cold washed over him, turning his stomach. He’d spent the last week subtly fishing for clues, trying to play it cool. Now, a hastily scrawled note lay on his kitchen counter, explaining a change of plans. Just a vague message saying the party was off.

He crumpled the invitation, its sharp edges digging into his palm. He walked to the window, the city lights a blurry, indifferent panorama. He felt a hollowness in his chest, a vacuum where excitement had been. He pushed the crumpled paper into his pocket and turned away from the view, suddenly not wanting to see anything. He went to bed early.
