Nothing Really Matters
NOTE: Six of One, Half a Dozen of the Other Day was original supposed to happen on 6/12, but it got bumped because of Invention Week.
You can still celebrate this special day on 6/12 or today (6/19). Either day is fine. It's a horse apiece.
How you celebrate the day is not that big of a deal either. You could do something related to the 6 or something appropriate for the 19 or the 12. Both (or is that all three?) work.
You could answer all questions you're asked today ambiguously. Or don't.
If you go out driving, you could make only left turns. Making only right turns is better, but you'll get there either way.
When playing a game, you could play as your usual color (red, for me) or you could play as a non-usual color. Depending on the game you pick, you might not have a choice. Whatever you use, just try to win, gracefully. If that's not possible, accidentally upsetting the game board is always an option.
If you need to use a search engine today, you could use Google or...yeah, just use Google.
