Earlier quoted context omitted.
Sure, but at some point, you have to be told what "duck, cover, hold" actually means. Your comment as the first comment someone hears is like a news article using acronyms throughout the article without ever expanding the acronym.
It's relatively self-explanatory. The full expansion would be " Duck under a table or other rigid object. Cover your head. Hold on."
I'm still not sure what I'm supposed to be holding onto. Do I briefly cover my head with my arms, then stop covering my head to hold onto the table? Do I hold onto my head while I cover it? Do I cover my loved one's head and they cover mine, sharing our last moments in a loving hold?
Now I'm beginning to wonder if I made a massive assumption that I would be covering my head with my hands. That's what I would do during a tornado, but maybe I'm supposed to be covering my head with a blanket so my hands are free for the hold on part?
Honestly, my facetious hold my bladder advice seems more apropos than anything I've managed to come up with for part three.
