Joe, I get a good laugh when someone says they need a Chinese interpreter. Being a hairy wide-eye barbarian myself, for years I thought there was such a thing. Now I'm told there is no language called "Chinese", you would be more successful at learning
Cantonese or Mandarin
which is the official language in Taiwan
French used to be the language of international diplomacy and is still spoken in a variety of odd places, but depending on where you are going...Spanish (or, again, some dialect of it) may be the most helpful.
Unless you can translate "Is there any problem with putting the torch and faggots in the bonnet?" you only speak US-Engish, not real English. <G> Not to worry, most of the world appreciates any effort you make at it, and if you have some type of computer or laptop
onboard, there are translation softwares out there which mangle all tongues equally. (Translate that, I dare them!<G>)
