This woman is extremely rude and obnoxious. Has she asked you exactly what kind of work you are doing with the animals or is she just so full of herself that she can make blanket pronouncements about your profession and for some reason, your character? I will be honest...I do not buy products from certain companies because of their animal testing practices and IF asked, I will talk calmly about it, but I am also friendly with a neighbor who works in medical research at the big, national known research university/hospital here and I have never vilified her for her work because that is what she does for a living, and my feelings are just that, mine. Unless you are a drug dealer or hitman, your profession is not up for debate, criticism or open hostility by anyone. As far as your Easter Egg Hunt, go for it, but do not invite her and if she says anything, be icily polite and tell her that her constant comments about your career are not what friends do to each other, therefore she is not welcome. If she shows up, you can tell her she is not invited and to please leave. And block her today.
