When I was a kid, I used to helpfully watch as my mom spent hours raking our whole yard by herself. When she was finally finished, she would warn me, "Don't jump in the leaves." I assumed she was trying to keep me safe from the man-eating leaf pile which would certainly open wide and swallow me whole if I jumped at it. Only recently have I realized that she only told me not to jump in the leaves because then she would have had to rake them all again. My mom can be so selfish.
Just kidding, Mom... you're the best! Sorry I didn't help you with the raking, but I've never felt comfortable around piles of leaves... as you can see.
