It started when my friend, Alex, invited me over for a study session. His mom, Mrs. Johnson, had offered to make us dinner, and we couldn't resist the promise of her famous lasagna.

"I've decided to take a class," she continued. "A class on...adulting."

As the night wore on, Mrs. Johnson regaled us with stories of her own teenage years, of rebellion and experimentation. It was clear that she was no longer content to simply be "the mom."
