Day 14 → A hero that has let you down. (letter)
I have been sitting on this for a few days (sorry about that) and I haven't come up with a darn thing. My hero is still my hero. They haven't and will never let me down despite all the dirty secrets I learn on a regular basis.
Sure I've been disappointed a few times over by people, but I never considered those to be my hero.
I wish I had a better juicier answer for your reading pleasure but I am pleased to say I don't.
