Other than cooking breakfast and some quick snacks, he does not contribute to the household. I tell him to put on more clothes if he is cold, but he complains to the point that I turn off the fans and air. My question is, don't I have a right to be comfortable in the home I pay for? I don't consider them social friends, and I don't think they need to know the details of my private life. Is there a nice way to tell these people to back off a little because we only work together?
