Fun fact, it's also Hitler's birthday.
And it is also actor George Takei (Sulu-Star Trek) birthday.....coincidence?
What meaning is in the "holiday?"
"Hey brah. Wanna smoke some tree? It is 4/20"
Why is this special compared to smoking in your garage on 4/19? There is NO MEANING.
Christmas is about a vast number of things. Hope, love, etc, Easter is about forgiveness and atonement. 4th of July is celebration of our independence and has a good bit of pride involved. Memorial day is a memorial. There is meaning behind these things that cannot be matched otherwise. Smoking pot with friends in your yard can be done every other day.
Couldn't the same be said about those holidays? I'm hoping you have love and hope every day of the year, same goes for forgiveness and atonement, as well as independence and some pride.
