My family always orders/makes food with avacados and I've said many times that avacados make my throat itch. Why do they keep doing this?

well if you cant eat that kind of foods . you dont really need eat whatever foods your parents makes for you. you can order your own foods like pizza or some thing you can eat. 

Because they like avocados and don't know they're supposed to care whether it causes you problems.

1. Ask your folks that same question, straight up.

2. Next time you catch them ordering something that's going to have avocado in it, speak up so you can get a portion without it.

They're waiting to see how long it will take you to find the correct spelling of avocado.

Don’t eat it and make your own food
