You should not invite a vegetarian for Christmas dinner if you have no intention of catering for them?
I am a vegetarian. I went to my MIL's for Christmas dinner and all I could eat was Brussels sprouts, peas, carrots and potatoes. Without gravy!
The stuffing, gravy etc.. all had animal products.
There were 14 of us in total and 3 of us were very disappointed vegetarians.
I usually host and make sure everyone is catered for. I felt quite irritated, as I had offered to bring any part of the meal and if she had told me she was not catering for the vegetarians, I would have done it.
My MIL is very traditional and supports fox hunting. I suspect that she does not agree with being vegetarian and this was her passive aggressive way of showing that.
In every other way she is lovely and a great MIL. She wants us to come again next year. How do I politely make sure this does not happen again?
