One day after school, I looked out the window at my house and then I saw a bright light. I thought it was an airplane so I went outside and looked. It was a UFO and there were billions of big green aliens coming out of the ship! I slipped on board unseen. They flew out of the ship on hover boards. They all look weird so I got up and followed them. One came over to me and said hi. I said hi back and then they ran! They got back into their ship and flew into space, back to their home planet.
