Je pourrais ecouter le français sans fin ...

Est-ce que il y a quelque chose on qui ne peut etre dit en francais et rentenir qui ne soit pas beaux :)?

I think you're just starting to learn french. Don't worry, it's a difficult language, but usefull and impressive. When you'll will reach a good level, you'll be proud, and satisfied of yourself.  Never give up ^^
