Thank you Al and Emiliano. I learned a lot from your code.
hari: no, it was just a stupid misspelling. English is not my native
language and though I understand it quite well my spelling needs
practice (or a spell-check).
And, yes... for my idea of the game it is important to make a six-pack
six individual bottles of beer. I'm trying to construct a game that
(as closly as I can) imitates a kind of "real life" where your
girlfriends mood changes quite a bit whether you've drunk one or six
beers (emptied the cat-litter, wore your shoes inside, vacuumed ...
and so on).

emiliano: the "instead of taking the fridge"-line. Are there benefits
there over making the fridge scenery or fixed in place?

Thank you again for very usefull information.
