Set default languages for Google Translate

Using "thou" sometimes helps, and so does "you all", but there is no foolproof way to get the correct form.

Google translate is based on statistical inference (not structural parsing / substitution), so the vous/tu usage is inconsistent.

you are very pretty -> tu es très jolie

you are very nice -> vous êtes très belle

I can only speculate "pretty" is more intimate than "nice" and more often encountered with "tu" forms in parallel translations Google's algorithms were trained on.

Get something like this keyboard with lower case letters printed on the keys so you don't have the problem of the mis-match between what he presses and what he sees on the screen. I don't know whether there is a Norwegian version of this or not.
