When you are a homo sapiens, you have four seasons (at least in theory if you’re living in the south): spring, summer, fall and winter.
When you are a box turtle, you also have four seasons: spring, estivation, fall and hibernation.
During two of your seasons, you will be out and about, active, eager to swim and hunt and snack and climb and run around and dig and destroy your outdoor habitat. And during the other two seasons, you will disappear completely from view.
This will then make your large shell-less mama very anxious and uncomfortable, which means you will have to endure getting dug up and checked out all over at least every other week or so while you are snoozing the unacceptably hot or cold weather away.
