Lily: I never got in touch because I was too embarrassed. I screwed everything up. I have no job, no place to live. I lost the love of my life. Look, I know I have no right to ask this but do you think Marshall would take me back?
Ted: In a heartbeat. If you called him up, yeah, he'd take you back with open arms.
Lily: Wow. So, maybe I should call him?
Ted: Maybe? No! This is... Ow! Hold on. Look. If you're gonna go back to him, I don't wanna hear the word "maybe". "Maybe" cannot be in your vocabulary. This break-up almost killed him. And he cannot go through it again. So, unless you're absolutely certain, stay the hell away from him.
