My friend Emma and I bought the same pair of shoes, but I could only wear one of mine. Four years ago, when I went skating with my husband, I didn’t know I would end up with torn tendons and a cast on my foot. When Emma came to Canada with her new husband, she had no way of knowing that their marriage would fall apart. You never know what kind of match you will make in this life. And you never really know what it’s like in someone else’s shoes.
