Quick question guys:
What is the exact meaning of "beating a dead horse"? I used to think (merely from having deducted it myself... or at least thinking I had) that it was something similar to "talking to the wall", but a couple of days ago I was watching a movie at home and stated to think I was way offfff... The translator turned it into Spanish as somethink like "despertar a los muertos" or something like that. When I thought of the Guns N' Roses song I started to see what it could mean, but I can't get the precise meaning...
