This riddle plays on the idea of falling and being hurt. "Falls often" refers to the way snow and rain descend from the sky, which is a common occurrence in nature. The clever twist is that while we think of falling as something that can cause injury, snow and rain, being natural elements, are not capable of being hurt — they simply accumulate on the ground or melt away. This juxtaposition of the physical act of falling and the inability to get hurt creates a delightful wordplay that makes the answer both logical and whimsical!
