Martin Luther King Jr.
Plain old Martin Luther (Yay Protestant Reformation)
I don’t think you have to change the world to be admirable.
My definition is very simple-
1) Someone that doesn’t have a stick up their ass.
2) Laugh often (Not sadistically or psychotically)
3) Their main objective does not consist of trying to engage you in intellectual banter
I don’t mind so much if someone has littering on their permanent record. Episodic lying or swearing also are permissible.
