Don't Put Your Cell Phone on the Dinner Table | Bon Appétit

"I learned from Mariah Grumet Humbert, a certified etiquette trainer and founder of Old Soul Etiquette in New York City, that nonverbal behavior carries more than half of how we communicate and that taking your phone out at a table often signals inattention. She thinks devices generally don't belong on restaurant tables (with exceptions for business meetings and solo meals) and urges us to evolve within our fast-paced world without losing kindness and respect — the bottom line being to make the other person feel valued. Her practical habits stuck with me: remove headphones and put the phone away when entering a space, briefly use it only to check a reservation or snap a drink photo, treat a server's approach as a cue to stow the phone, and if needed keep the phone on your lap under a napkin set to vibrate; she also suggests asking yourself if you'd take a book out at that moment as a way to resist the impulse to use your phone." - ByMaggie Hennessy

Mariah is top notch in her knowledge of all things etiquette. I especially love the recommendations she gives for conversation starters while entertaining. I had a style session with Mariah, and again, her knowledge and insight was so helpful. Mariah is a bright light in our world. Combining her knowledge, her enthusiasm, and her inner joy, I would highly recommend her classes for any age. You won’t be disappointed!

Mariah's etiquette advice is wonderful advice for both children and adults. We all need social etiquette reminders from time to time, especially in our ever changing world. Mariah is so pleasant and easy to to listen to, but don't be fooled by her sweet and kind demeanor - she is also a dedicated, strong and focused business owner and she is helping to make our world a better place!

I wasn’t raised in a decorum rich family but have always tried to put my best foot forward. As someone that will be 63 this year, I know I would have had a better life experience having the delivered knowledge so articulately and sweetly shared as Mariah provides. She brings genuine joy into my being.

Old School Etiquette is a gem! It is so refreshing to have someone that stimulates the younger generation to WANT to embrace how to be comfortable in any setting. I enjoy all Mariah’s tips and techniques, and I highly recommend her services!

Mariah should be followed on instagram by everyone! She gives short, concise tips on being polite and having the appropriate behavior in a variety of social situations. There is a strong need for her coaching in our society!

OSE is bringing back a lost art that should be common knowledge to all. The name should be Beautiful Soul Etiquette, because Mariah has a lovely way to teach the foundation of basic manners and kindness. Her content is easy to read and follow!

Mariah is so very charming and professional. We took a tween etiquette class for my son. She not only graciously accommodated a scheduling error(our fault) but held a wonderful online session. He still remembers the lesson tips. The world needs more kindness and manners and her advice could help anyone and everyone incorporate grace and manners daily in small and approachable yet modern ways.
