Chemistry and Timing
Ted: I used to believe in destiny. You know? I’d go to the bagel place, see a pretty girl in line, reading my favorite novel, whistling the song that’s been stuck in my head all week, and I’d think, “Wow, hey — maybe she’s the one.” Now I think, “I just know that bitch is going to take the last whole wheat everything bagel.”
Robin: You’ve just been focused on work.
Ted: No. It’s more than that. I’ve stopped believing. Not in some depressed, I’m-gonna-cry-during-my-toast way. Not in a way I even noticed until tonight. It’s just, everyday, I think I believe a little less, and a little less, and a little less, and that sucks. What do I do about that, Scherbatsky?
Robin: You’re Ted Mosby. You start believing again.
Ted: In what? Destiny?
Robin: Chemistry. If you have chemistry, you only need one other thing.
Ted: What’s that?
Robin: Timing. But timing’s a bitch.
