Question: Your friend is OCD and has to have things in a particular way. She even labels her socks so that the sock for the left foot will always be worn on the left foot and vice versa. Why did she lace her left shoe with a brown lace and the right one with a green lace?
Answer: So that she will always know which shoe each lace is for. Since the left shoe is currently laced with a brown lace and the right one with a green lace, she knows that the other brown lace is for the right shoe and the other green lace is for the left. The question tells you that she is very particular about which foot things go on but says nothing about colour.
