Sometimes kids do the same thing over.

When my 15 year old was about 8 or so, we moved to our home where we live now. We got mats to put out at our doorstep to wipe your shoes. As time goes on and the mat gets older it tends to curl up a bit on the end. My son is somewhat clumsy, as I'm sure I've said before. Well one night while running up the front steps to the porch he tripped on the mat and sorta spread out on the porch. He was fine and nothing major. Well 3 days later he comes running up the front steps hits the mat and says, " Stupid mat! Not again!", as he trips on it and tumbles in the door. Luckily the only thing hurt was his pride.
