Time travel

I heard a knock on the door, I got up and walked to the door and stood on my tippy toes looking through the hole to see who was there. I saw a man. I have no clue who this guy is. His style is very different compared to today's. It's not bad or anything just a little different....

He's a tall man, very skinny with tan skin, he has shaggy dark brown hair. I dropped my feet landing back on my heels debating if I should answer the door. My gut was telling me not too. I mean all our lives we've been told not to open the doors to strangers or even speak to them, but something in me wanted me to open the door. I took a deep breath and unlocked the door. My shaky hand rested on the doorknob for a brief moment. I twisted the brass handle and opened the door fully revealing the man. He's pretty lanky and has beautiful green eyes. To be honest he looks a lot like me. Just a bit older and well...a man. "Oh-my-god It's really you!" His scream is the first thing that came out his mouth and from there he never shut up. He began to ramble about him building a time machine with his mother named Mia. Something I've planned to name my child if I was to have a girl. "I've been looking for you for like 200 years! You don't understand the joy I have right now! Mia was- well is I mean not now but will me and like was because in my times she's dead but like I-sorry I lost focus. um.. her name stuck with the family for a while after she died, stuck in the family up tell I was born, I'm the first boy born in the family in ages! But guess what?!" I stood there puzzled not knowing what to say or what to do. "Don't play with me boy it isn't funny. You're a grown man! You shouldn't be acting like a kid pulling pranks on people." I said with a stern voice. "No! you don't get it you saved the world!!"

"I didn't save the world." I frowned getting irritated with this man.

"Yet" he said holding his finger in the air.
