Just a short comment on the difference of 'ti' and 'chi', as mentioned in the course, lesson three fro Mark Nodine. I do not agree, that "this distinction has largely dropped out... at least under the age of 40...". As in other languages having this distinction I think it is still kept alive at least when people don't know each other yet. I agree that younger people switch to the 'ti' form quicker than older people, but from my point of view this happens even earlier with speakers of French or German, where in the latter case e.g. students use the familar form as a signal of "being of the same social class". For example I would address any student with "du" in German, even if s/he is 30 years old, but address an employee at a baker's shop with "Sie" in any case (even 18 years old). Similar observation I made in (North) Walian Welsh. Please correct me, if I'm wrong (Dydw i ddim yn siarad cymraeg fel mamiaith chwaith) Johannes Heinecke
