"Who's there and how much did you see!" Tom said should I say something or just be quiet?! I didn't notice my feet walked out "I may or may not have followed you" I said he walked out of the water "what are you doing here?!"he asked "i- I was cut off with he hit me with a rock and everything went black
(3 and a half hours later)
I woke up in my bed? I sit up and my head hurts badly! I walk downstairs to smell dinner *farther? Dad?" Then farther and dad run in "thank God" dad said "what happened?"  They looked at each other then farther said "a boy knocked on our door with you in his arms he said he saw you in the woods out cold and we thanked him. He said he had to go so we said goodbye and he left "okay? How long was I out?"I asked  "about 4 hours" dad said I thanked him and went to my room I had to know more about that boy I thought and tired to remember what happened but all I remember is those dark blue wings and that I love him and want to be his
