The exact same degree of "sad" as allowing a 6 year old child to believe in The Tooth Fairy.
What harm does it do? Them being less than "accurate" with the day they celebrate whatever? How does it impact your personal existence Illini?
You wanna sit them (
and that 6 year old) down adminiter a "lesson" to them and shatter their illusions? For
what gain?
Rip from them a few moments of joy here in the House of Pain for what? to show off
"Wisdom"?
Which would you consider more valuable?
That little bit of Happiness for them or one's Ego getting a little snack? A snack like an
egg ball
that leaves one hungry 4 seconds after downing it
but the price for which was ripping away joy from a wide eyed 6 year old or from a god only knows how many Christians whose celebration of whatever on an "incorrect day" has no impact on your life whatsoever?
