Hi, Craig.
>AHh.. yes.. well, if you're talking about names ("proper nouns"), it's easy. Try to do it with general nouns (how do you say "house" without making it the feminine la casa?). It gets even worse with adjectives, (casa blanca), where both the noun and adjective are feminine.
Well, that doesn't imply gender in the sense of male/female and all of this "neutral" intention. Just for the record, is "el agua" masculine? You know the plural is "las aguas". Spanish has a lot of nice intrincancies. ;-)
Good Spanish, by the way. We may try next time talking we meet!
Cheers,
