" You cannot predict a person's sudden passing, but there are certain people in life that you prepare yourself to lose, for whatever reason. You foolishly try to protect yourself by building a wall around your heart as a sort of preemptive defense mechanism so that when you get that call, you are prepared somehow. Like being emotionally vaccinated, you have already built up an immunity to their inevitable passing.
But this never works. "

― Dave Grohl , The Storyteller: Tales of Life and Music
