Robin: Well, Ted, what else did she said? Did she gave you any kind of explanation?
[flashback to Ted and Stella in her office:]
Stella: Look, after Lucy was born, I dated a little, but it was hard to find a guy I could trust enough. Sooner or later, every one of them gave me a reason not to.
Ted: But nobody in five years?
Stella: Look, Ted, guys regret the girls they didn't sleep with. Girls regret the guys they do sleep with. And for the past five years, I've had no regrets. Ted, you're staring at my boobs.
Ted: In my defense, they were staring at me.
