In my mind there's two category of fruit. Jewish fruit and Pure fruit. For example, orange, tomato, kiwi and pineapple are jewish fruit. While on the other hand apple, banana, dragonfruit, mango are pure fruit.

Am I retarded or do some of you also differentiate fruits like this?

@MK2boogaloo I think it's entirely possible that even if others do this you are in fact retarded.
