LOL, I did exactly the same thing when I ran into her in Scotland!On a less argumentative point- I turned around in my hotel restaurant last year and went totally fangirl inside at seeing Margaret Atwood at the next table. I didn't let my husband converse with me at all, as I eavesdropped on her conversation about autographing kindles. She seemed like a fascinating woman to spend time with.
I found Oryx and Crake interesting, but I didn't connect with it. At all. Largely because of the male protagonists. I liked Year of the Flood a lot. MaddAddam was only okay -- too unfocussed, and some character points that bugged me, but not a bad end to the trilogy.I didn't much like Oryx and Crake, but from the sounds of it, Year of the Flood and MaddAddam improve on it.
