Dear Alexander,
It can be hard to keep saying no. Sometimes it's difficult for friends and family members who are used to sharing foods with others to remember that you might not be able to eat the food they are offering. You're doing the right thing by turning down the food. And while it may seem like a pain to have to keep reminding people, try to remember that if they aren’t living with food allergies every day, it's probably not something that they immediately think of; instead, they probably feel as if they are just being polite by offering you food.
The next time this happens, you could simply say, "No, thanks. You might remember that I have a food allergy and I can only eat something if my parents have read the label and told me it’s okay."
