Well I guess english or swedish or any other western type languge could be considered difficult to japanese or chinese speaking cause they are so different to eachother. But if you think english is wierd you should try as suggested japanese or thai. Thai is wierd [img]i/expressions/face-icon-small-smile.gif[/img] like 5 words spelled the exact same way but depending on where you put pitch or pronounciation (however that is spelled) it means 5 different things. And can become pretty wierd if you say the wrong thing.

Think all languages have their wierd sides for an outsider trying to learn or understand, especially the grammar and pronounciations of things. But as allready said children exposed to dialekts and languages can pick them up pretty fast if they have someone arround them that can explain what the stuff means [img]i/expressions/face-icon-small-smile.gif[/img]. I was born in Norway and picked up Swedish when I moved here allthough its almost the same but different in just a month or so, and my dad had english and american friends arround often so that helped alot in speaking english pretty early in life.
