The return address read, "Northwood High School Reunion Committee," and a wide smile bloomed across her face. "Oh, this is going to be fun!" she exclaimed, tearing open the invitation. A flutter of excitement filled her chest; she imagined seeing old friends and reminiscing about the good old days. Her fingers tapped excitedly on the glossy paper as she scanned the details of the event.
