i tought a class of foreigners today, and they turned out to find the swedish vowels very difficult. so i promised to talk more about vowels on friday, and to bring some exercises for them, but i couldn't find anything interesting in the bookshelves at the school. and neither of the other teachers i talked to had anything to recommend... so i'm now searching the net for interesting things about swedish vowels. unfortunately it's much harder searching the net now that my back is not co-operating... i can't sit still very long, and i get impatient and give up quickly. soon i'll have to come up with something myself, which is probably much less work when i think about it...
