It’s only natural for siblings to compare themselves (although maybe not with an Excel table). But since we work together, Red often wonders if that makes the natural tendency of older siblings to be bossy even more extreme as Black’s “technically” her boss. Black simply sees us as a team, personally and professionally. But we do agree that, in honor of National Sibling’s Day, we should all celebrate our siblings …

Of course, there's Mother's Day and Father's Day. But National Siblings Day? Really?

BANTER BITE BACKSTORY: Could there be a more perfect day for Red & Black than National Siblings Day, except maybe National Sisters Day (that's the first Sunday in August) – but who creates these days anyway?

We'll be honest. We had no idea there was a Siblings Day until Black, who typically never celebrates holidays, decided she at least should know when holidays occur and found Holidays Calendar. There she learned the history of National Siblings Day (it was begun by Claudia Evart in honor of her siblings – both of whom died tragically), but continued her research and ultimately sent Red a Fact Sheet, who found the facts interesting but was genuinely touched by the first bullet point,

Siblings Day follows the spirit of Mother's Day and Father's Day – a great family tradition and celebration of family values. It is an uplifting celebration honoring people who have shaped our values, beliefs and ideals.

Because for all of Black's sarcasm and no-nonsense pragmatism, Red genuinely wouldn't know what she'd do without her sister. Yes, she took Red's crisis and turned it into a book, a brand, and a business. Yes, she's the first person to stop Red's seemingly endless warm and fuzzy, blah-blah-blah (this is Red's description of herself). But Red also knows that no matter what, Black has always been there for her, and always will.

On the other hand, Black has always taken the approach that she can say (or even do) whatever she wants to Red, that's a sister's prerogative, but heaven help the person who tried to do anything to her "baby" sister. And although Black may not "volunteer" niceties about her sister (she prefers the role of big sister explaining how she had to "rescue" Red at the age of 40+ because she was, to be blunt, financially clueless), Black will admit that Red sharing her "crisis" (Red's word, Black prefers "life experience") with others to help them avoid making the same mistakes she made, has made her sister her hero. Which, for those who know Black, is really saying something.

So, whether you and your siblings are as different as Red & Black or have a lot in common, remember that today is the "official" day to let them know how you feel about them!
