Time Traveller from year 2050

It was a typical day in the year 2045, or so it seemed for John, a scientist working for the Time Travel Division of the World Government. He had spent the past several months working on the design of the new time machine, a device that would allow people to travel through time and experience history in ways that were previously impossible.

John was one of the few people who had been selected to test the new time machine, and he was eager to see what it could do. He stepped into the device and set the time coordinates for the year 1963, the year of the Kennedy assassination. The machine whirred to life, and suddenly John found himself transported to the streets of Dallas, Texas, on that fateful day.

He looked around, amazed by the sights and sounds of the city in the early 60s. The sky was blue, the air was crisp, and the people were dressed in the latest fashions of the era. John felt as if he had stepped back in time, and he couldn't wait to explore.

As he wandered the streets of Dallas, John found himself drawn to Dealey Plaza, the site of the Kennedy assassination. He watched from a distance as the President's motorcade approached, and he felt his heart racing with anticipation. Suddenly, shots rang out, and John watched in horror as Kennedy slumped over in his seat.

John couldn't believe what he was seeing. He had read about the assassination in history books, but to witness it firsthand was something else entirely. He felt a sense of helplessness wash over him, knowing that there was nothing he could do to change the course of history.

As he stood there, lost in thought, John suddenly felt a hand on his shoulder. He turned around to see a man standing behind him, dressed in clothes that seemed out of place in this era.

"Hello there," the man said, smiling warmly. "My name is Alex. I couldn't help but notice you seem a bit lost."

John was taken aback. He had been so caught up in the moment that he hadn't even noticed the man approaching him.

"I'm fine, thanks," John said, still feeling a bit dazed.

Alex smiled again. "You're not from around here, are you?"

John hesitated before answering. He knew that revealing his true identity as a time traveler could have disastrous consequences.

"No, I'm just visiting," he said, trying to sound casual.

Alex raised an eyebrow, seeming to sense that John was hiding something. "Well, if you ever need a guide to show you around, just let me know. I know this city like the back of my hand."

With that, Alex walked away, leaving John feeling more bewildered than ever. Who was this man, and how did he know that John wasn't from this time period?

John shook his head, trying to clear his thoughts. He knew that he needed to be careful, or he could risk altering the course of history. But as he walked through the streets of Dallas, he couldn't help feeling a sense of excitement at the possibilities that lay ahead.

Over the next few days, John continued to explore the city, meeting new people and experiencing life in the 60s. He tried to keep a low profile, but he couldn't help feeling that he was being watched.

One day, as he was walking through a park, John saw Alex again. This time, he approached him.

"What do you want?" John asked, his voice filled with suspicion.

Alex smiled, seeming unfazed by John's hostility. "I just want to help you," he said. "I know what you are, and I know why you're here."

John felt a chill run down his spine. How could Alex possibly know
