The weightlifting session left a pleasant ache in his muscles, the endorphins coursing through his veins. Mark, fresh from the gym, felt utterly alive, the world around him vibrant and clear. A package, addressed to "Ms. Rodriguez," sat by the front door.

He strode into his kitchen, heading straight for the fridge. A meal made of protein and carbs was his reward. He looked at the package, and shook his head with a grin. He was going to completely ignore it for the rest of the day.

He took a bite of his food. His whole body felt alive. This was truly the best.
