Do you speak English?
When I arrived in England I thought I knew English. After I’d been here an hour I realized that I did not understand one word. In the first week I picked up a tolerable working knowledge of the language and the next seven years convinced me gradually but thoroughly that I __would never know it really well__, let alone perfectly. This is sad. My only consolation being that nobody speaks English perfectly.
Remember that those five hundred words an average Englishman uses are __far from being the whole vocabulary of the language__. You may learn another five hundred and another five thousand and yet another fifty thousand and still you may come across a further fifty thousand __you have never heard of before, and nobody else either__.
If you live here long enough you will find out to your greatest amazement that the adjective nice is not the only adjective the language possesses, in spite of the fact that __in the first three years you do not need to learn or use any other adjectives__. You can say that the weather is nice, a restaurant is nice, Mr. Soandso is nice, Mrs. Soandso’s clothes are nice, you had a nice time, __and all this will be correct__.
Then you have to decide on your accent. The easiest way to give the impression of having a good accent or no foreign accent at all is to hold an unlit pipe in your mouth, to mutter between your teeth and finish all your sentences with the question: “isn’t it?” People will not understand much, but they are accustomed to that and they will get a __most excellent impression__.
