The watch

What now, part 6

After throwing the watch, Jim and I ran outside, freaking out about what we just saw. I didn't want to go back to my room with the watch, but I was curious about how it works. I asked jim what we should do but he was too stunned to talk.  I started walking slowly to my room, curiosity took the best of me, and I wanted to see the watch again. Jim slowly followed, when we got to my room, we picked up the watch. We wanted to learn more about it, how it works, what we can do, why no one can see us when we went back, and how I got hit with a car, but didn't get hurt. This is weird, but we decided to do it again. I remembered I failed a test a few days before, so I wanted to see if I can go back that far. I pressed the button and said "take me back to 3 days ago on my test". Next thing we knew we were in my class. I tried talking but no one heard me, I was curious, and I had an idea. I pulled a paper out of my pocket that said hey, and threw it at my past self. It hit me and phased through, like Jim and I.
