The aroma of freshly mown grass and the distant thwack of a baseball bat filled the air as Robert sat on the porch, enjoying the late afternoon. His son, Ben, was usually out playing baseball. He had heard his son practicing, earlier. He had been so proud.

He went to his son's room. He noticed his son's phone on his desk. He picked it up, and quickly found his social media account.

He found a series of posts where Ben shared his baseball statistics, his excitement for the upcoming game, and his passion for the sport. He felt a light sensation in his chest. His son had his own world, his own passion. He felt a warmth as he realized how driven his son was.

He went outside to work in the yard, whistling a cheerful tune. He was delighted.
