As your wife, I was also the recipient of mean comments because of my religion.
And yes, the office space was small so if they were not sure I overheard them,
they would go to my desk and repeat again whatever comment or question they made
each other. It was not easy to be professional but there is no other way to face
that problem. At the end, after some years of working there, I was able to get
along with all except one. I moved to greener and nicer pastures and do not
regret leaving that job for a minute. One may say it's the golden
opportunity to talk about religion, to clarify missunderstandings, etc but truth
is that can't happen when chances are it will turn into some kind of a
battle. As I always responded to them: I will answer your question when you
really want to sit and have a nice discussion about it leaving criticism and
mocking aside. It never happened. So I guess, they were never interested.
