DS was at his friend's house the other day, this is the first time he has eaten there. I called the parents to let them know that DS was vegan, and they said they would make sure he didn't eat any milk/eggs/meat etc.
DS came home feeling unwell, and covered in a rash, which is what happens when he has milk. Long story short, the mother told me she thought it would be a nice treat for him (ice cream), and she of course wouldn't have done it if she knew he had an allergy. She had told DS it was dairy free ice cream.
AIBU to think that she was rude to actively go against my wishes, and that it shouldn't matter why DS is vegan?
I feel like if you cater for someone, you should respect their dietary wishes, whether they are for health, religious or ethical reasons, or nay other reasons.
