okay this was crazy as soon as i walked into computer science class my back was killing me and plus im sore and i think im sore from the tug of war i did yesterday because i havent worked up by arms like that in a long time. But me and my friend Victoria needed a back crack. so we tried using the chairs and lean back which mine crakced but hers didnt so we laed on the floor and i called my friend sofia which she is good at cracking your bones becasue she did victoria first and she cracked her back instantly. Then it was my turn so i layed down and boom she pushed down once and boom my back cracked so loud, she did my middle back and it felt so good. My back feels good but then i realized my shoulder and arms hurt so victoria looked up how to crack a shoulder but it didnt work so i thinj im just sore.
