Ouch! Michelle Obama opened up about her own social media practices at an event on Tuesday, Feb. 27 — and seemingly dissed President Donald Trump‘s tweets in the process.

“I still haven’t figured it out because I’m old and I don’t understand most of social media,” she admitted during a health panel at Klick Health’s MUSE New York, according to People. “I tweet, but I have a committee. I don’t just tweet off the top of my head, which I don’t encourage people to do — especially kids.”

Michelle continued, “How many kids do you know that the first thing that comes off the top of their head is the first thing they should express? You know? It’s like, ‘Take a minute. Talk to your crew before you put that [out there] and then spell check and check the grammar.'”

She then made a subtle jab at Donald’s well-known obscure tweets. “I think kids do think telling it like it is and talking off the top of your head [is cool]… [but] that’s never been good. We weren’t raised like that. That’s rude. That’s what you call rude. But yes, I use social media. But I use it like a grown-up,” the mom-of-two claimed.

We’ve been hearing Michelle’s voice on social media for years, and in November, we’ll get to hear it even more through her new memoir, Becoming. She shared news of the exciting project via Instagram earlier this week.

“Writing Becoming has been a deeply personal experience. It has allowed me, for the very first time, the space to honestly reflect on the unexpected trajectory of my life. In this book, I talk about my roots and how a little girl from the South Side of Chicago found her voice and developed the strength to use it to empower others,” she wrote. “I hope my journey inspires readers to find the courage to become whoever they aspire to be. I can’t wait to share my story.” And we can’t wait to read it!
