You missed Catalan, which is probably the most romantic of romance languages.
Actually 'Romance' as in languages has nothing to do with romance as in love. It comes from the Vulgar Latin word Romanice (Roman or Romanicus in Classical Latin)
The language of the troubadours was Occitan or Langue d'oc. France's education system has pretty well killed it one now though, although some Monegasques still speak it.
Aquest' amors me fer tan gen
Al cor d'una dousa sabor:
Cen vetz mor lo jorn de dolor
E reviu de joi autras cen.
Ben es mos mals de bel semblan,
Que mais val mos mals qu'autre bes!
E pois mos mals aitan bos m'es,
Bos er lo bes apres l'afan.
This love hits me so deliciously
in the heart with its soft taste
that hundred of times a day I die
from my pain and hundred other times again
I relive of joy.
I suffer from a sickness that I find so wonderful
that I prefer this evil to any other good!
And since my sickness is so delicious for me,
how much more will be good the happiness
that will come after it!
Mandarin Chinese is easy once you learn the tones. It has very little grammar. The written language is 'just a tad' more difficult to learn though, and you forget the characters very quickly if you don't use it.
