In that analogy where life is compared to a roller coaster, which part is supposed to be the fun part - the excruciating, slow going up where you are waiting to fall or plummeting into the abyss?
[Gil has been complaining about his complicated life; Grandma wanders into the room] Grandma: You know, when I was nineteen, Grandpa took me on a roller coaster.
Grandma: Up, down, up, down. Oh, what a ride!
Gil: What a great story.
Grandma: I always wanted to go again. You know, it was just so interesting to me that a ride could make me so frightened, so scared, so sick, so excited, and so thrilled all together! Some didn't like it. They went on the merry-go-round. That just goes around. Nothing. I like the roller coaster. You get more out of it.
Karen: I happen to LIKE the roller coaster, okay? As far as I'm concerned, your grandmother is brilliant.
Gil: Yeah if she's so brilliant why is she sitting in our NEIGHBOR'S CAR?
