Please answer the following question: I'm taking a test and have to guess the right answer to the question after the article. Article: In the United States, friends can be close, constant and real. But if they move live far away from each other, little by little, they will not be as close as before. But 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 two people meet again by chance, even years later, they will be delighted and pick up the friendship again. In America, you can feel free to visit people's homes, share their holidays and enjoy their delicious food. If you are invited to a party, just accept their hospitality for various reasons, such as crowded space, language difficulties or family customs. It is often considered more friendly to invite a person to one's home than to go to a public place. So, if your host or hostess brings you home, do not feel that you aren't treated well. You know, strangers are not invited into the home. _ if you do not find flowers awaiting you in your hotel room either. Flowers are very expensive there, hotel delivery is not certain, and arrival times are often delayed, so flowers are not often sent as a welcoming touch. Please do not feel unwanted! In fact, signs outside change in different lands, but the welcome in the heart is real and valuable. Question: You will find friendships _ in America if they are not near each other. Options: A: die suddenly B: come back C: disappear gradually D: last forever
