"Ready?" Ben practically shouted into the phone, his voice echoing with enthusiasm. He was putting the finishing touches on his apartment, transforming it into a gaming paradise. The latest video game, an exclusive pre-release, sat waiting on his coffee table, surrounded by snacks and drinks. His best friends would be arriving shortly.

He had planned the perfect birthday. Pizza, gaming, laughter โ€“ a simple, yet perfect celebration. He had arranged everything, making sure everyone knew the exact time and location. The thought of the competitive spirit and camaraderie fuelled his excitement.

A message appeared on his phone. It was from Mark, confirming attendance to a rival party at a bar, and "that it was going to be awesome." Ben's excitement wavered, replaced with a subtle, yet distinct, feeling ofโ€ฆ something akin to disappointment.
