And this is where Clark & Lois work so great together. If Clark is trying hard to nail a corrupt politician, or if he writes a novel that doesn't sell, or if he has to bury his father...these are things Lois can relate to. Things she can offer support & strength for. Obviously there are things she can help him with in his Superman career, but I'm talking things on a cosmic or mythological scale. He fails to save a hostage at a bank heist, he can talk to Lois. He fails to save the lives on a distant planet that Mongul annihilates, there's no way Lois can comprehend that. She can listen, and be supportive, but she can't comprehend it any more than you or I could comprehend a nuclear physicist ranting about his bad day at the office.
