    Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while—then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us develop more slowly but then become lifelong feelings, reaching deeply into both families. Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be happier if we accept their hospitality(友好) easily.

Another difficult point for us Chinese to understand Americans is that although they treat us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts（主人）, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to  our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily life. They will probably expect us to get ourselves from the airport to our hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real.

We will find ourselves treated hospitably.

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for only business matters. So accept their hospitality at home!
