To make sense

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 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 just true.
You love him, and he loves you.
And that doesn't have to make sense to make sense.
