Its like Port Adelaide and Adelaide Crows mortal enemies but both proud South Australians!

Also Collingwood and Essendon mortal enemies but also both proud reps of their State.

Eagles and Dockers both play the same game but are mortal enemies but proud members of their State.

Labor and Greens mortal enemies but work proudly in the interests of their country.
