A single mother fed up with her son's bad behaviour penned a letter to him and posted it to Facebook - with a huge response.
After lying about his homework, telling his mother she wasn't the boss of him and declaring he could pay his own way with earnings from his YouTube videos, Estella Havisham responded to her 13-year-old son with a note outlining expenses he should contribute to.
"Since you seem to have forgotten you are only 13, and I'm the parent, and you won't be controlled, I guess you need a lesson in independence," she wrote.
The following letter, which Havisham says she accidentally made public, received mixed responses of support and criticism.
