In the iconic Star Wars saga, R2-D2 always seems to save the day, getting his Jedi masters and the forces of the Republic out of harm's way, and doing so with grace and humor. But the astromech droid never gets the full credit or honors he deserves for his deeds.
In that sense, R2 is a stand-in for all of the under appreciated and unheralded heroes in our everyday lives -- in our workplaces, schools and communities.
We should all join together on a national holiday to pay homage to those who, like R2, live by the "selfless, not selfish" creed.
