How overcome informal communication problems?

Informal communication is typically referred to as a casual conversation with a friend. Usually the topics that are discussed range from a variety of subjects such as what one had watched on TV last night, to what one plans to do in the upcoming weekend. If one feels that they are having problems coming up with such a casual conversation with somebody, then the best thing to do would be for that person to practice things to say well before talking with that person in order to well prepare themselves in advance.
