rhony’s returning!

They’re back.

Bravo’s Real Housewives of New York City — Bethenny, Carol, Dorinda, LuAnn, Ramona, Sonja and Tinsley — return April 4 for Season 10.

Say what you will about our reality divas, like the fact that none of them are married and therefore not technically wives — house or otherwise, but after a decade, there are lessons to be learned from these Manhattan ladies. (Please stop laughing and allow me to make my points.)

Actions speak louder than words. Bethenny dubbed Ramona “the Apologizer,” because the bug-eyed blonde always expresses regret after one of her nasty outbursts, which seem to occur every episode. Yes, she always seeks forgiveness, until next time when she does the offending behavior again. Mea culpa is meaningless unless actions back it up.

Alcohol is no one’s friend. Slurring, stumbling and just plain falling down drunk, even if you’re swaddled in Escada, is not a good look; especially if, as with Luann, imbibing results in battery on a law enforcement officer, resisting arrest with violence, and two counts of corruption by threat. Pretty sobering, huh?

Tell it like it is. I don’t know when letting every piece of stupidity that pops in one’s head, fall out one’s mouth started masquerading as “honesty,” but in the world of RHNYC, that’s the definition. Being unfiltered seems to be OK only when one is dishing it out, though. When one is on the receiving end, well, being frank is called hurtful, rude and “mean girl.” In the real New York, as opposed to realty land, you don’t dish it out if you can’t take it.

Diversify. It all began with a margarita. Then Bethenny’s Skinny Girl logo showed up on wine, got slapped on salad dressing and popcorn, plus appliances like blenders. Every time we turn around Bethenny has a new gig — currently it’s house flipping, which she got Bravo to turn into a show. The entrepreneur has also been a talk show host as well as Shark Tank judge. She gives new meaning to the phrase “side hustle.” When you have more than one way to generate income, no one job can hold you financially hostage.

Make it nice! A paraphrase of Dorinda’s “I made it nice,” rant, but all the housewives adhere to it when it comes to entertaining. Whether it’s a house party or catered affair, each lady’s soirees are well-attended, the food and pinot flows like Tinsley’s golden curls, and they always overdress for the occasion, as in, It’s my party and I’ll wear an “I Dream Of Jeannie” high ponytail if I want to.

Don’t be all, like, uncool. The Countess nailed this one. No explanation necessary.

Saying it makes it so. You live on the top floor of a building, refer to it as the penthouse. You go out a lot, assume the title of socialite. (The actual definition of which is “a person who is well known in fashionable society.”) And, in Sonja’s case, come up with a lot of unfeasible business ventures, pretend they exist, and represent them collectively as your “international luxury lifestyle brand.”

Strike while the iron is hot. What do you do when you realize you suddenly have a following? Launch a recording career, a wine company, a clothing empire, a nail polish line, a shapewear company, jeans brand, or write a book (the “as told to” kind requiring a ghostwriter).

Ya gotta have friends. When they’re not screaming, fighting, pot-stirring, making passive/aggressive digs, talking over each other, schooling one another on appropriateness, stealing each other’s boyfriends and business ideas, and dishonoring the “girl code,” they have each other’s backs. Even Bethenny showed up to support BFF-cum-enemy and former housewife Jill Zarin at her husband’s recent funeral.

When life knocks you down, get back up. Carol and Dorinda lost their husbands to illness. Luann and Ramona have been cheated on. They, as well as Sonja, Bethenny and Tinsley have been embroiled in Page Six-type divorces. Some of their businesses have bitten the dust. Houses had to be moved from, and possessions sold off. Custody battles fought. Health issues remedied. Yet, they’re all still here, every Wednesday at 9 p.m.
