Nice info there yukio_michael san !! I wish I could be a little richer than I am--of course not to insinuate something beyond the truth, to the likes of my presently being 'rich' or something.
Now I'm working on a plan. For the past 7 weeks I have been doing a lot digging around my place laying a lot of pipe, a 1500 liter tank system for collecting rainwater and building a rock retaining wall to hold it all. (and all that digging was by hand !!!) So my plan is to create, and then whirlpool a new pet rock sensation here in Japan. I have a couple of small mountains of rocks collected up now from all that digging. All I have to do now, is get my boys to wash them one by one, glue little pop-eyes that roll around, on them, and paint a kind of smile. Then I'll be rolling in dirt, I meant dough, in no time at all !!! hee, hee, hee......yeah....in my craziest dreams, huh?!!
But seriously, one can get rich here if things click right--even in the teaching business. Nice post yukio !!
