Let's see - the reptilian side of the brain reacts with the patronising "I did it first syndrome" = territoriality >:-)

Haha oops I just realised what that comment of mine must have sounded like, i really like your article - it is extremely detailed and awesome!!

I didn't think to check Sydney specifically! Have read it now - looks like you had a good discussion on Sydney etiquette!
