What is a one-sentence summary of the following article?
If you can sense that your friend does not want to talk about something, turn the conversation back to the activity you originally planned, or suggest a new activity. It is not your job to be funny or interesting.  Experts say that the conversations that people find the most interesting are the ones where they are able to talk about their own interests the most.  All you have to do is ask your friend about what interests them, and listen carefully, so you can ask follow-up questions. If your activities don’t work out, suggest something that you usually like to do. If all else fails, take a walk or get food. Don’t let changes ruin the visit. Remember that some of the best visits are not centered around an activity at all. Activities are really just an excuse to hang out and talk.  If the two of you are having a good time without doing the activity, don't rush into doing it.  If the conversation ever runs out, the activity will be a good way to break the silence. Don't expect to be best friends as soon as the visit is over.  Just be confident in the fact that you were able to successfully ask someone over, and keep doing it until it becomes second nature.

Summary:
Don't let a moment of awkwardness ruin the visit. Be flexible and spontaneous. Remember that some friendships take time to grow.
