Chin up Paul, I had a similar experience in the summer but not quite as dramatic..... pulling out of a layby when the person (femme and not the lodger :o ) I was riding with decided to stop ahead of me as i was doing the shoulder check! Result, a long front wheel darky followed by a short punt into her back wheel before a battle of balance trying not to drop the bike. I felt exactly the same as you at the time, more annoyed than anything.
I've just put it into the list of 'experiences i wish i hadn't had' and have carried on having learned from it.
The main thing is I hope it hasn't put Jane off.

(I should imaging, given your mass that there was a fair bit of momentum exchanged from your bike to hers during the collision phase :rolleyes )
