Everyone's hardcore until their father's on dialyses

 So right now everyone's cutting out their heart so they can function as a real-life automaton. Trouble with that is that no one actually is hardcore deep down. The more strong they appear on the surface, the more stuff is going on underneath. Almost as a rule. 

But the point is that when someone you love dies, or falls ill, there's no greater pain. Try as you might, you just can't "toughen up." Bad things happen to good people all the time. Bad things happen to bad people too. Bad things happen all round, and this is life in a nutshell. 

So rather than trying to be the hardest person in town, maybe try softening your heart and seeing which feelings creep up. Otherwise you're just waiting for trouble to come along.
