Any language that is spoken too quickly, bothers me. I don’t like hearing Chinese, because of the ups and downs of the inflection. German bothers me from a strictly emotional point of view.
ARABIC MAKES ME SICK. Period.
Other than English and Hebrew (or Aramaic, which is beautiful also), my favorite language to hear spoken is Italian, because it is a melodic language, and I agree with “babytalk” because I’d love to hear ANYTHING my new ainekal will babble when he is able. This, above all.
