Dear Katelyn,
I feel so sorry that your enthusiasm for Britain has been so corroded by what, from what you say, appears to be the general unfriendliness of my countrymen. You say for example:
"British people even talk to us sometimes. Not often."
"It's as if I've tried and tried to be a good guest and all I get is sneers and sniggers."
"Accept the gulf between us and "them," and get on with things."
Would it help at all to discuss these feelings in greater detail, perhaps giving instances? Whilst I am by no means the best advocate in the world for my fellow Brits, and find them often as infuriatingly cold and aloof as do you good Americans, it may be that in some of your experiences of them you have read them wrong, or they have read you wrong; or at least there may have been some misunderstanding or breakdown in communication. But it is difficult to tell unless actual cases are discussed.
Again, I am so very saddened that your dream seems to have been shattered. If there is anything I can do by interpreting the ways of Englishmen to you, to help rebuild your enjoyment of my country for your remaining months as our guest, I'd take it as a huge honour.
Yours most sincerely,
Howard
