Today I took some glass bottles to be recycled. We recycle quite a lot in my home. My sister who moved out this year was very big on the environment and recycling.
The ground next to the recycling bins was covered in broken glass. Bits of glass stuck to my shoes.
Now if I had come home and kept my shoes on, what would have happened? What effect would the small particles of glass embedded in my shoes have had on the carpet or any kind of floor?
Do you see what I am getting at?
