The stupid parts:
An astute member of the community gently points out that it's actually just half the world, and serena_skylark defends herself by saying, "I just don't remember what countries have the summer season except Australia."
When iheartretards (I gotta admit, I have much love for that username) accuses her of being dumb, she excuses herself from the realm of the educated, saying, "I've never lived in those countries or even visited them".
EDIT: Aw man, I'm a retard. Sorry, sorry.
