It flummoxes me to no end, this whole Northern vs. Southern Hemisphere dichotomy where seasons are concerned. I made an utter fool of myself at work, I'm certain, with the expressions of unchecked disbelief expressed when an Australian coworker patiently explained that yes, they celebrate xmas in the middle of summer.
A point of reason, yes- but one I'd never stopped to consider. "So July is...WINTER?" I flabbergasted.

Self, meet ethnocentrism.
