Most grown-ups know that adulting seems deceptively easy when viewed through the eyes of an inexperienced child, and if you don’t, you should take note.

There’s a nicely powered home to live with features like food on the table and unlimited internet use. And how those things got there isn’t nearly as simple as a child might believe.

One mother, wanting to teach her disrespectful son that “nothing comes for free” found a hilarious way to call out the 13-year-old who wasn’t ready for the responsibilities of an adult.

In 2015, Heidi Johnson was having trouble with her defiant 13-year-old son Aaron, who she writes “wants the perks of growing up without the responsibility that comes with it.”

At the time, Aaron was earning a “teeny tiny bit of money” as a YouTuber and refused to follow his mom’s instructions about completing his homework. The young rebel stormed out of her room and declared “he was a free person” as he was “making money.”

Responding to his behavior, the single mother penned a tough love letter to Aaron and shared it on Facebook, a post that after almost 10 years has gone viral again.

Since you seem to have forgotten you are only 13, and I’m the parent, and that you won’t be controlled, I guess you will need a lesson in independence,” Johnson begins in the “roommate contract.” “As you threw in my face that you are making money now it will be easier to buy back all the items I bought for you in the past.”

She added, “If you would like you lamps/lightbulbs or access to the internet, you will need to pay your share of the costs.”
