And that's the problem. Being Superman isn't a job for him it shouldn't be. He should enjoy being Superman. It shouldn't be a chore he is relieve from to hang out with Lois and Jimmy. Superman wanting to be a normal guy is a cliche. A forced attempt at complexity. An attempt at justifying relationship that just won't work long term because it will inevitably grow stale. The universe is so vast and he has complete access to every corner of it but you want me to believe that he rather spend the evening working in the farm, doing the ditches or watching Lois do the laundry? If I had my way Lois would have married someone else. Clark would have allowed her to get on with her life while he explored the universe and helped people.
