Hope you feel better. I think you are perfectly right to tell her not to mention the pups again. If it is an employer-employee relationship, then you are not her therapist. Don't bring up the topic, but if she does, then cut her off, telling her that it upsets you and that you don't want to hear about it ever again. And, if she forgets, keep cutting her off and reminding her. You aren't paying her to come and upset you.
