Your mother is a guest. So you're right.
May your arguments with your wife only be about this.
My mother doesn't care what type of of food it is my daughter & I that want davka American or Ashkenazi food.
We do generally deli or burger joints.
I just said if you want mideastern crap you are welcome to stay home but my daughter & I want American food to which my daughter says Tatty why are you so mean to which I reply I am not being mean I am just being pushy so I get what I want.
She then is cool but every year the same deal.
Imagine we went to a Chinese restaurant & my wife asked for pita & chumous & techina.
This is our biggest arguement.
I don't eat deli the rest of year so once a year I can have what I enjoy as can my daughter.
