Facinating stuff, kids. For instance, did you know that there are three dimensions of love? Intimacy (warmth and closeness), passion (sexual desire), and commitment (the decision to maintain a relationship in spite of differences).
And those turn into eight profiles of loving relationships: Non-love, Liking (only intimacy), infatuation (only passion), empty love (only commitment), fatuous love (passion and commitment), romatic love (passion and intimacy), companionate love (intimacy and commitment), and consumate love (intimacy, passion, AND commitment!).
It's so funny to see something so big this broken down like this. I haven't decided if it's a helpful tool or an oversimplication. Probably both.

In other news: I asked a teacher I work with how he was doing today and he replied: "perfect!"
"Really!?" I exclaimed, slightly incredulous.
"Oh yes," he answered, "I'm getting perfecter every day."
I love this answer more than any other.
