Love is exactly the same. It's there, it's always there, it's what's keeping it all together. Without love, everything falls apart. You only notice love when it hurts you, but that doesn't mean that love always hurts. It's just that with everything that's going on in people's lives, they don't notice the love that's right there. It's only when they make mistakes, stupid mistakes that could have been avoided if they'd paid attention to the love that was right in front of their noses, that love starts to hurt. And then people blame love, instead of taking responsibility for what they did themselves, and decide that they're better off without love. And then-- then they fall apart.

So I can't tell you if I've ever been in love, because being in love is a perpetual state of existence, not something that happens once in a while.

I like that. It's true. It's only when we start capitalizing Love in our minds that it gets tricky and hurtful.

Also, yes. Yes, the universe humors the Doctor. And, no, that really isn't fair ;)
