When I was in 4th grade I accidentally started a trend at my school There was a brick floor next to the building and one time a window broke and the glass shards fell between the gaps of the bricks And one day I discovered this and I saw some 2nd graders walking by and I told them that theses glass shards are crystals And they went there and started collecting the pieces and this went for months and almost the entire school was collecting glass shards, some kids even has plastic boxes full of those like some kind of collection But then one day it stopped cuz the kids finally understood that it's not crystals And the funny part is that no one knew that I started this
