Situation: I am standing on the second step of the stairs to grab the box on the table that is in front of me.
Alternative situations: I walk back to the stairs, where I place the towel in the box on the table next to the foot of the stairs. I am standing at the second stair landing holding on to the handrails with my hands, the cabinet is to the left at the bottom of the stairs.
Question: What can I do in order to pick up my backpack?
