The thought of seeing everyone made Maria want to jump with joy. Her cheeks were flushed, her eyes bright. This party, her loved ones, the whole thing would be perfect. She was practically bubbling with anticipation.

A text, quick and devastating: *Postponed. Sorry.* A brief flicker of shock crossed her face.

Maria bit her lip, then let out a small laugh. She’d always wanted to go to that museum. She changed her plans. She looked at the date and time. An afternoon to herself. Perfect.
