My partner works very hard behind the scenes on a well-known television crime procedural.  Yesterday, D gets home from a 14-hour workday at 2:30 a.m. I begin to complain solipsistically about the mountain of papers and exams I have spent the day grading. 

D sighs: "Tomorrow I hope I have time to take a shower. My hands are all covered in blood." 

Pause.

He glances over at me absently. 

Then, urgently: "Fake blood. Fake blood!".

Is this a fairly common conversation to have with your beloved?
