He felt a tingle in his fingertips, a sensation he hadn't experienced in years. The notification, a digital slap in the face from Mark, the bane of his school days, seemed to ignite something within him. He leaned back in his chair, stretching his arms above his head, feeling the satisfying crack of his spine. The world, once painted in shades of gray, now exploded with vibrancy.

He closed his laptop, abandoning the endless spreadsheets that had been his lifeblood for so long. The urge to do something, *anything* other than work, was overwhelming. Grabbing his keys, he headed out, the spring air filling his lungs. He walked, he ran, he jumped, he danced. The old park near his house called to him. It had been years since he had felt that light.

He found himself smiling at the squirrels, the children playing. He opened the friend request, ready for anything.
