Hi everyone! Today a native American teacher has told me that "Ann's reading now" is incorrect because you can never contract "is" if it's used after a proper name because it will only mean possesion (genitive - so, in this case, it would mean something like "the reading of Ann", which does not make sense at all). This is the first time I hear something like this. Can native speakers confirm that this is true, please? Thanks a lot for your help!!
