'bound' for disaster?

Happy Hump Day!

Thursday's nightlife column is about new rules for breakup etiquette. OK, no more details. I'll leave you in suspense for the next 24 hours.

Something I thought about including in the column -- but didn't -- is the idea of a rebound relationship. A friend recently told me that there's no such thing as a rebound mate, since every new beginning comes from some other beginning's end.

(Yes, I did just quote "Closing Time." Have a problem with that?)

I think the "rebound" category classifies mainly-physical relationships that are used to mask emotions from a former heartbreak.

That said, do you think it's possible, and not at all sketchy, to genuinely fall for someone one week after a breakup? One day after a breakup?

At what point is it just a new relationship and not a rebound?
