I tripped in the parking lot at work today, very ungraciously, and fell hard on my left knee. My skin is very scraped up (to the point of bleeding), but my thin cotton dress pants don’t have so much as a pull. This has happened before, most recently when I was wearing jeans at the ballpark and scraped my knee on some concrete but did absolutely no damage to the denim.
How is that possible? How could my knee be scraped and cut but the cloth covering it be pristine?
