Wahuh?

I just watched a lady pull up in front of SF General Hospital and parallel park her forest green Mitsubishi Montero. She got out of the car, got her dog out of the back seat, walked up three cars, and got into a black Montero, in which she promptly drove away.

I wonder if she has 2 just to mess with her neighbors:

"Don't they have a green Montero too?"
"I've never seen two Monteros parked outside. And why would they have 2 colors of the same car but never bring them both home at the same time?
"I guess you're right. I must be losing my mind."
