 Nobody was home. I was home by myself. I was carrying a laundry basket. I don't remember what was in it, but it could have been towels. It could have been clothes. I don't know. How much could a laundry basket full possibly weigh? Four pounds? Five pounds? Based upon the size of the laundry basket. Well, it was just a regular size laundry basket. I'm holding it with my two hands. I'm walking up the stairs. I get to the landing. I start climbing the second set of stairs.
