Yeah, Phineas and Ferb really set the bar high.

Winter is best month bc:
Inside, AC is usually warmer than necessary (I prefer warm to cool), plus, if it snows, then you can make an adventure out of that and go do snow-stuff (well, I would, cause it don't snow in Georgia that much); there's no pressure to do something crazy and cool, just maybe buy some people some Christmas gifts (and that's if you take yourself seriously as an adult); and you get New Year's after that, which is a great way to feel like you're getting a fresh start; it's comfortable to wear a zip-up hoodie to bury your face in outside and wear loosely inside; etcetera, etcetera, I could go on, but I got a fucking stomach virus an it's late.
