Well written, but pretty much all 'yucky' stuff.

Clark does grovel well.

I can just see the sequel now... Lois finishes the letter, and allows herself to flash through a myriad of emotions, but settles on 'having it out with Clark face to face'. A sly smile comes across her face as she throws open the window and jumps out, expecting Clark to catch her and hold her in his arms. It's then that she remembers that she had absent-mindedly closed the curtains just as she was beginning to read the letter. Clark, thinking she didn't want to see him, has flown off. Poor Lois... splat!
