Jack's physically clumsy but emotionally together whereas Ennis is the opposite. It's funny that he cites his clumsiness as a reason not to take the power company job, since he always comes across as competent at everything he does as long as there are no emotions involved.
I see Ennis as really competent, too, ww (and I find that part of his magnetic sexiness); and I always wondered about that comment of his about being clumsy. Obviously, as everyone has said here, it was just to brush Alma off about getting a "regular" job.
I liked the list posted above, about how well Ennis did things and what a klutz Jack was, bless his heart. But needless to say, Ennis was lacking in emotional and social skills. A classic example of two who, together are one perfectness.
