There is a gulf of differing intentionality between squat and hunker-down. Squatting is often used. One squats to look at the dandelion, one squats so as not to tower over a child, or squats, of necessity, in the woods. One hunkers down - which is the same physical act essentially - in order to tolerate a period that is irresistibly over-whelming. We seem, now, to be in the interim period where we see that it's time for others to "hunker down" but believing that we don't have to do that yet. As the Doser said some time ago: This is the time for the UAW to put something on the table. As the Governor said, it's time to levy some demanding fees on ourselves. As an op-ed person said, it's time for the Oregon Teachers Association to ease up on their demands. As Metro Councilor Rod Park said, the convention area hotel isn't a possibility now.
The "irresistibly overwhelming" has arrived when I know that I must hunker down now. The Oxford English Dictionary tells me how to do it: “....squat, with the haunches, knees, and ankles acutely bent, so as to bring the hams near the heels, and throw the whole weight upon the fore part of the feet”. The advantage of this position is that we're not only crouched close to the ground, so presenting a small target for whatever the universe chooses to throw at us, but we're ready to move at a moment’s notice.
