So my brother is very kindly hosting us and my parents over for Xmas. They are vegetarian, we are. In this case, they will have a nut roast as the main alternative to a turkey. The snag is that my immediate family are all allergic to nuts. DH thinks it's rude of them to have it as the main - am less bothered. Am sure my brother doesnt see it as rude - they just arent as bothered about allergies. DH and DDs allergies are severe enough that if they accidentally ingested nuts- they will need an epipen.
