History can't be destroyed

jack looks at me concerned, "why would there be blood tea in the kitchen? I don't understand...I've been knowing her for a 3 years from now and I guess there are some things I don't know about her...I'm a bad friend.." I pat jack on the back."jack it's gonna be fine and you're not a bad friend and to me you're the best friend I could ever have!" I hug jack. "come on, let's get back home, you know what they say when little kids go out alone at night, they get kidnapped." I nod and take jack's hand. as we walk jack asked me more about the blood tea. "so....this so called blood tea, you're talking about, did something happened after you drank that tea? "I don't think so but I saw a bunch of shadows and I thought some people were trying to scare me but no it was real. one look at them and then...they're gone. but I did see two ghosts that looked like siblings; sister and sister I mean. it looked like I've seen them before but I couldn't remember of where I remember them. it feels like my memory has been erased!" then after we were done talking we cross upon a building in the middle of the woods. and next-door to the building that was a "4 minute walk" and it seemed to be like an old witch tent. we went split paths. I went to the old witch tent while jack went to the unknown 4 story building. I search around if there was anything useful that could have explain the past events that happened in that house. then I found a box but it needed a key. I looked around to see if there any key. nothing. I continue to look though these witch stuff and found a tiger's eye. I heard it's a good luck crystal. I put it in my pocket. and found a bag of lavender. I may not be a witch but I know what all of these items mean. it's better to know your luck and your bad luck if not, you may expect some things coming your way. I get out of the tent and run to the building with the box. I went inside the building and saw jack on the 3rd floor. I saw him just in this room full of keys. I think he needed to find the key for this box but he didn't know that. until he heard my footsteps and found out it was me and look at the box. he knew that he needed to find the key for this box. I examine the box and it had some details on the box. there was some flowers and thorns on it. and it said the word numbers. then I knew what I needed to do; me and jack needed to work as a team. the details on the box were telling us that the key would be as the same as the chest but I still don't get the number part. "JACK!! FIND THE KEY THAT HAS FLOWERS AND THORNS ON IT!!" jack ran to the the other side of the room and found 6 keys that were the same. I he toss one at a time. I tried the first key to fit it with the box. and didn't work. jack tossed me another key and that didn't work. I wonder if there is 6 keys and 200 keys in total I would have do 6 divide by 200 is...I stop in my tracks if I did this math problem in head without evening knowing how many keys were there in the room I guess I'm too smart for a 13 year old myself. so basically the answer would be 0.03 and I look back at the recent keys and that I a certain amount of flowers. one had 15 the other key had 11 flowers. not the thorns that matter but the flowers do. I need a key with 3 flowers on it. I told jack the past on the rest of the keys. he threw them all at once I was able to catch them all. I looked for a key that had 3 flowers on it. but nothing. i throw the keys in anger and then I couldn't have sworn that I heard a key in the bag I was holding. I open my bag and there lies a key. I use the key for the box and it worked! I don't know how that ended up there. "JACK!! come here! the box opened" jack runs across the room and sat next to me. I open the box....
