Quote from Lily in Last Time in New York
Lily: Hey, Ted?
Lily: You wrote down all these things to say goodbye to, but so many of them are good things. Why not just say goodbye to the bad things? Say goodbye to all the times you felt lost. To all the times it was a "no" instead of a "yes." To all the scrapes and bruises. To all the heartache. Say goodbye to everything you really want to do for the last time. But don't go have one last Scotch with Barney. Have the first Scotch toasting Barney's new life. Because that's a good thing... And the good things will always be here waiting for you. What?
Ted: Turn the page.
Lily: "Get one last life lecture from Lily." Well, you're dreaming if you think that's the last one of those.
