國中英語基測出現過 letter 的考題。

Dear Mr. Hush,

I just learned over the radio that you feel as bad as I do about the way people use their cellphones. Very often in public places, people speak loudly on their cellphone, and we have to hear about other people’s business. But who cares about that? Not me! Why should I know the life of people I don’t even know? It’s really nice that someone famous like you speaks out for a quiet living space.

And it’s even more wonderful to know that you yourself always talk quietly when you have to use the cellphone in public places. Thanks for NOT sharing what you are talking about. We have shared too much noise already!
