See? A ship has arrived with goods that need to be unloaded. Notice what the people are doing. Theyu2019re simply lifting the crates and carrying them.
If one canu2019t manage alone, two people take it, sometimes three or even more. By the time they unload everything, theyu2019ll probably have used up all their strength.
I spent many days thinking about how I could make their work easier, and it turns out the answer was right in front of me…
