"What?!" Tom exploded, his voice cracking. He re-read the invitations, the words swimming before his eyes. His two best friends, Jake and Kevin, had both decided to celebrate their birthdays on the same day. He felt his face turn ashen.

He paced back and forth in his living room, his hands clenched into fists. He had already bought presents and RSVP'd to both events. Now what? His head swam.

He felt a sudden, inexplicable sense of vertigo. His carefully planned weekend had been shattered. He ran a hand through his hair, tugging at the strands in frustration.

He stood there, a mixture of disbelief and utter bewilderment washing over him. The world seemed to tilt on its axis. He felt a profound sense of helplessness.
