Let's be real, summer is not that fun. It's oppressively hot all the time. You get to choose between freezing inside where there's AC, or dying outside where it's literally hell on earth.
Summer might have been fun when you were a child. Three months off to just hang out is always a plus. But now you're an adult and get to see summer slip away from the office window (if you're lucky enough to have a window).
Literally any season is better than summer, if only because those seasons don't promise to be magical. Summer is more hype than anything else.
Others don't give a shit about what people are saying about summer because they're too busying enjoying the good weather. Why complain about the heat? Embrace it! Half the year people are freezing to death, so what's wrong with a little sun? It's the perfect time to go to the beach, the park or that far off destination you've been wanting to go to for ages.
And of course, there's no school for at least three months for those lucky enough to still be in school. That's three months without homework, projects, teachers or anyone telling you what to do.
