Kiki - why do you think we like the Germans more after the World Cup? Which World Cup? Actually, I don't see that it has affected matters either way. We found our narrow victory in 1966 quite amusing, and are a bit upset about how well the Germans usually do. I don't think most British dislike the Spanish, French or Germans, but just don't see the need to learn their languages. They learn ours, so why bother?! Especially when, as you so amply illustrated, our efforts are generally not appreciated and usually get raised eyebrows...
