I still don't understand this attitude of "I can't be bothered to try to understand it so it's useless". Vietnamese is actually one of the more easy tonal languages for westerners to understand, given that the tone marks are literally pictograms of the pitch (and it's not a transliteration like 你好 -> nǐ hǎo). Why are you so allergic to actually making use of that feature?
