As a language teacher I have to disagree.
( I teach German, French and English)
I`m talking about Switzerland in the following and of course there are exceptions to my statements:
French natives hate learning German more than anything else.
Swiss-German natives hate learning French more than anything else.
But now and then there are students that like that language and what I observed is:
Even if a French native loves German, his level of proficiency in German is lower,than that of a German native that hates French in French.
And that`s not because I teach French better or anything. TheGerman language is just not as regular and grammatically more complicated.
What do you think about that?
