Asking questions is one way to keep a conversation going. Another way is to give factual information to the other person. This allows people to learn more about each other and the kinds of things they might have in common.
Factual information is the kind of information that tells someone who, what, where, when, and how.
Greet the person. Give some information to the other person. Judge if the other person is listening and is interested in pursuing the conversation. Telling someone at the Community Residence about an outing planned for the weekend. Telling a friend about a movie or TV show that you saw recently.
