The relationship between Americans and the British is quite interesting. On one hand, both sides look down on each other, with Americans thinking that the United Kingdom is outdated, while the British view Americans as nouveau riche.
On the other hand, both countries are predominantly Anglo-Saxon and share many common interests, which creates some complex connections. As such, both sides enjoy purchasing properties in the other's countries.
But the British tend to buy large estates in the United States, while Americans are accustomed to buying historical buildings in the United Kingdom. In summary, both sides seek what they lack in each other's countries.
Therefore, it is quite common for wealthy Americans to come to the United Kingdom to buy historical houses, especially when the estate purchased by Mr. and Mrs. Lewis is located near Cambridge, which reflects the owner's taste very well.
