Quote from Ted in The End of the Aisle
Robin: I... I can't shake it. I-I can't shake this feeling that nothing about me and Barney makes any sense. Ted: But love doesn't make sense. I mean, you can't logic your way into or out of it. Love is totally nonsensical, but we have to keep doing it or else we're lost and... and love is dead and humanity should just pack it in. Because love is the best thing we do. Look, I know that sounds cheesy, but it's-it's just true. You love Barney, and-and he loves you. And that doesn't have to make sense to make sense.
