Harris used to be a sort of man who used to take the burden of everything on himself and later put it on the back of the other people. Describe

In Chapter Three, Harris volunteers to write out the packing list, and J. compares him for the reader to his Uncle Podger, who always volunteers to help others but bungles the job because he is so accident-prone. Thus, helpful as Harris tries to be, his inability to finish tasks ultimately makes more work for everyone else.
