You literally that you can’t comprehend why anyone would cry in that situation. And yet, presumably, they did, so obviously you’ve got a problem trying to understand how some people’s emotions work.
People cry for a lot of reasons. I’m sure you wouldn’t understand it in some cases either. This does not mean we have a problem. However, considering Fallon’s show, and the circumstances, I am going to assume (a bad word, I know) they are of the generation that cries over everything. I find this more plausible than a producer suffering from some form of PTSD and Norm worship.
So basically “darn pussy kids need to man up and stop crying so much.” Okay cool.
