Once you have made the first move and uttered the first word when making small talk - there is no turning back. You need to keep things going - at least for the next couple of minutes or so - before you can gracefully say your goodbyes and make a polite exit. So what do you talk about in the meantime? Think about the things that you yourself would like to share to a new friend and that is what you can ask the other person about. Work, family, where they live, and their hobbies or interests are some general points of discussion. To keep the ball rolling, you can use follow up questions to show that you are really interested with what they have to say. Restaurants, movies, music, news, the weather, traffic, favorite tourist or vacation spots are other things that you can use as small talk topics of conversation. Once you find common points of interest, things will definitely take off from there.
