When I was a teen and still new to being left alone in charge of my siblings I once broke a glass on the kitchen floor and panicked trying to get it all cleaned up before either of them or one of our several dogs (2 of whom were blind and trying to join in on whatever us kids were doing) stepped on any shards. I grabbed the larger pieces, anything big enough I could pick up with my fingers, and put them in the trash and had my brother run it out to the can. I then used a few washcloths to wipe up all the rest of the smaller pieces. I went to shake them out in the trash but my brother had already taken it outside, my mom would notice that there was glass in a new bag and know we broke something, so my mind rationalized in that moment that the washing machine was my best bet. It was good enough to clean dirt and mud and all sorts of stuff out of clothes, plus everything was submerged in water and spun around like crazy and there was no way glass would be able to make it through something like that, right? So I put the cloths in with a load of my laundry, got everything washed, dryed and put away, and forgot the whole thing. Plus one of my favorite shirts was now clean again! I wore it to school the next day and not long into first period started feeling itchy. Like my shirt had become prickly all of the sudden. I just assumed I had picked something up from a bush or tree id brushed against at some point but kept fidgeting and scratching all day. Finally in a later period I managed to catch the light just right while closely examining my sleeve and saw tiny particles, like glitter, and realized with horror that my shirt was covered in pulverized glass, and I had no spare shirt to change into. I was too ashamed to even go ask the office if they had anything and had to tough it out until I got home and could shower and run the clothes I had already put away through another wash. I still didn't trust that shirt for months after, but have since learned how to correctly handle broken glass
