I am going to tell my wife she isn't allowed to go to Paris for work.
Why don't you think your wife can go on the trip to Paris?
It's expensive, the food quality there is poor, and I fear that she may be assaulted
It's wonderful that you're worried for your wife's safety there, but you need to support her and her work. It's important for her to be independent, and you not supporting it all is rude and limiting her. This may be the key for her getting a higher salary and you might ruin it.
You're taking her side! I thought we are a team.
No, I am not. This is her job and she has to go and you need to let her.
