I said "when are you coming to the house". The answer given was "When are you coming OVER to the house". (Not "when are you coming home" as stated above, so now the discussion answers do not match with the reality of the practice info!). Still..."When are you coming to the house" vs. "... over to the house" seems perfectly correct.
Naturally. The 1st point I made was that the answer given from the English perspective is not normally used. The 2nd point made is that the answer under the question they gave above, is not even the same answer as given on the lesson page...which was "when are you coming over to the house". (i.e: discrepancies between lesson page answer and what is being stated on this discussion page are not even the same).
