I’m visiting a few people in a week or two and am hoping to stay with one of them.  My potential host is unsure his hosting capacity as he’s visiting relatives the week before and may not recover in time.  I find it mind-boggling that a social interaction could be so personally draining that recuperation could take a whole week but then I tried adding context.  My host is capable of doing a pull-up, I can’t.  I wonder if he finds it equally mind-boggling that someone would be physically incapable of pulling his or her mass from the ground.  I checked this logic with a 3rd party:

Him: You’re totally off base.
Me: What do you mean?
Him: Pull-ups can only be performed with the aid of a superhuman stunt double or possible a wire team.
Me: When did you come to this conclusion?
Him: 5th grade gym.
