Firstly, the book about the English mentioned in "Das Klassensystem in England" was probably "Watching the English" by Kate Fox. I haven't read it, but it sounds like it analyses English or British behaviour in an entertaining way, telling you things that you kind-of knew before but hadn't ever realised or analysed.
Secondly, I can update you on the squirrel from "Seed Protection". I thought I had beaten it and saved some nuts for the birds, but a few days after the last post, it got its revenge. I had been out in town and came back to find the feeder on the ground in tatters. It had been gnawed away quite considerably, and was in 3 pieces, with the cord used to tie it to the tree also severed. I would have liked to see the shock on its face when the feeder fell out of the tree, probably with the squirrel attached. But ultimately it won and I can tell you that I won't be messing with squirrels again any time soon
