I can't believe that I was an adult when I first learned that seasons are not universal, and I don't mean that July is winter in Australia but summer in Europe.

I can't believe that I was an adult when I first learned that seasons are not universal, and I don't mean that July is winter in Australia but summer in Europe. I mean like how in Mali, there are three seasons: the wet (rainy) season from June to mid-December, the dry season from mid-December to March, and a hot season from March to June. The epiphany I experienced was kind of like the one I had during a software engineering class, an exercise in internationalization where students had to write a program that took people's names as an input (which turns out to be quite complicated). It always amazes me how many unexamined assumptions our minds make about how the world works, and it always surprises me when I run into one.
