For sure. And as it so happens I'm slogging through Mandarin right now with Rosetta stone. Just enough to get by, but my understanding is that they're more interested in learning English than the other way around. Plus, and I've just heard this through the grapevine, they consider it insulting when you try to speak their language - in general. Might be a stereotype though.
Either way, I'm not enjoying Mandarin. Not even a little. My voice goes up an octave when I try the pronunciations and I can't seem to make it stop. The syllabic ups and downs are killing me.
