There's a lot in common that we Americans have with the British. But there's a lot that goes on in each culture which will completely mystify the inhabitants of the other. I quite enjoyed this cartoon that came over in The Nib today.
Now I can tell you that there are as many things about Brit culture that are every bit as puzzling to us Yanks. I could describe to you the horrors of a hotel breakfast buffet, including safety-yellow fish. I'm a breakfast guy, but I made do there with toast, jam and coffee.
And for gawds' sake: I dearly wish they would get their story straight on just WTF is a "pudding?"
