I don't know what you're talking about. Although raising a family might be your personal life, it is seriously HARD WORK. Just because you love your family, doesn't mean you don't work hard to provide for them. My parents, for example, are foster parents and so we have about 6-7 children around the house on average. Because of this they are always on the run; cleaning the house, keeping the children busy, paying bills, running errands, cooking food, supplementing what the children learn at school, and making sure to give the children a chance to go outside and play with others while supervising other's children. This is hard work. On top of this, they want to improve their household and themselves. They also run a foster parents association to help others in the area. Because of all of this, they don't usually go to sleep until 1-2am each day, to balance all of this. This is what I truly call HARD WORK.
Now, they could do what the author says and call it quits after 35 hours (what a fucking low # btw) of taking care of the children and running their organization. They should be proud of the amount of work they do to keep their family together and improve themselves. And you shouldn't be whining if they happen to make a twitter post about it. It's not your business.
