My mom has always been strangly supportaive of things I get obsessed with. She's even read the Twilight series and is planning on going to the movie with me (she went to the Breaking Dawn release party with me, too). And instead of getting annoyed with me everytime a shout "Volvo!" when we're driving down the street, she joins in, it's become a game of sorts to see who can spot the most Volvo's, and if you fine a silver S60R you win
. She let me buy honey colored contacts even, so I could look more like the Cullen's. So all in all, she cool with it.
