I traveled there as a teenager in the 1970s to see London and the usual tourist sites. I went again to see different parts of the country during my military career. I neglected English travel during the 1990s to favor more exotic destinations. But finally this year I returned as a businessman, bringing two employees with me. I thought you Czechs might enjoy reading an American's view of England.
Language is a good place to start.
I will readily admit that the English are more careful to use correct grammar than Americans. American choral teachers often praise the English pronunciation of vowels, and encourage our singers to imitate it. Although the English have many good qualities, good dental health is not one of them. Of course, because I am a dentist, I may notice it more. Perhaps it is the fault of their socialistic dental care system.
