Sheldon:
I’ve devoted the prime of my life to string theory
and it’s quest for the compactification of extra dimensions.
I’ve got nothing to show for it, and I feel like a fool.
Penny:
Okay. I get it.
I mean, not all the jibber jabberin in the middle, but…
I know what it’s like
to put your heart and soul into something
and get nothing out of it.
Sheldon:
You mean your acting career?
Penny:
No.
I’m saying
you and string theory sound like a relationship,
and I know what it’s like to be in one
and realize it’s never gonna turn out the way you want.
Sheldon:
Well, what do you do?
Penny:
You have to have the courage to end the relationship,
You know? Break it off, shake hands, walk away.
Sheldon:
I don’t know if I can do that.
Penny:
I know it’s hard, honey, but in the end,
that’s how you grow.
