La Japoneisa: "Yes but what do I do?" "Hide under the table."

Is what you do when an earthquake comes.
That was Renchan`s professional advice upon my panicky phonecall this afternoon as I got woken up, all by myself bang in the middle of Tokyo on top floor of our building, to the house moving from side to side and backwards and forth.
First thing I remembered was that you are supposed to stand yourself under the doorframe and so, wondering why that could be but knowing no better, there I stood, one hand holding onto the frame of the door, and the other, shaking, in panick trying to find Ren`s phone number in my mobile.
He picked up and sounded as if nothing was happening, and then, upon my adrenalin driven and rather intense question of `But what do I do?!` he just burst out laughing and while laughing his head off he told me to hide under the table.
There you go. That`s what you do if you ever wondered what was it that you do when an earthquake comes.
