Head like a lumber-room...

My mother has told me I have a head stuffed with useless knowledge. That's probably true, but I read long ago about how the sea recedes just before a tsunami (in James Michener's Hawaii, I think it was) and I never forgot that creepy possibility. Might come in handy some day.

Here's the story of a 10 year-old girl who saved her family and 100 people, just because she had that same tidbit of knowledge from having done a school report on tsunamis ( story, her picture). I'l have to remember this, for when my children complain about school projects.)
