Well, we've got seasons! We take cues from the weather, and nature. When the snow melts and it starts warmin' up, you put berries in the ground. When it starts coolin' down and the leaves change color, you start makin' sure you've got plenty of firewood. It's a cycle! And you may not know EXACTLY what the weather's gonna be like on any given day, but... well, it's not gonna snow in the middle of summer, right? Haw! Well, unless you get an angry Abomasnow, I s'pose.
