My eldest son just got back from university but still doesn't have a job. He says that he wants to stay at home for the time being and he would get a job within 2 months. I let him stay for no rent, but it's now been almost three months and he hasn't gone to many interviews. I've asked him about his plans for the future, but he gives me evasive answers. He says I shouldn't make him pay rent because I'm his mom and he's going to move out soon, but I'm not sure. Should I start making him pay rent?
