Real life rules don't apply in animal crossing. Whoever thinks it's normal to place bushes in front of their house is discouraged to do so in this game. It saddens me greatly of all these stupid invisible rules. I can't build a freaking bridge because two villagers houses on either side are too close together for that. I can't place pwps too close to a villager house. This is ridiculous. It would be nice if they changed this with the new update for acnl in December but I doubt it.
