Yeah - I would never've thought crepuscular meant that - I was going more for the way old ladies skin looks around their eyes, kind've baggy and soft and infinitely folded, or maybe something to do with oysters ... which now that I look up the Pocket Oxford Dictionary I find that it might be to do with oysters in the zoological sense of the word ie being active and etc at twilight.

Now I'm not totally sure that oysters are active at twilight, but I can imagine them getting together for a few drinks and a quiet chat around the hardwood posts down at Towra Point.

Maybe just active when it's high tide and twilight.

Poor Romans having to do romantic things when it was "crepuscular" , thank goodness that the English came up with a better word. Good on us.
