Well, in the first book, when Hagrid brings baby harry to Private street, he said to Dumbledore that the muggles had started swarming around the house. Then in DH, when harry visits godric's hollow, he sees that muggles can't see the house.
So, if the muggles can't see the house, then hhow come they started swarming around them?
don't u think its strange??
