I'm having a hard time seeing that (joke ) or comment being anything.
I imagine it came up in the context of ...how are you holding up? ...ok the first day ... had some struggles yesterday and....blah blah ... THE POINT of it is /was ...this has been hard and is getting harder with each day .....maybe harder then he plan for or expected. So what if he express how that discomfort has been building wrapped in an exaggeration (joke). You want to critique his communications style....today. Right now he stuck doing all the heavy lifting ....I give him all the slack he needs or wants. I think her lack of communication is fueling this ....not anything from his end.
