Open-ended questions to start a conversation

I. Ask an open-ended question.

1. "What sort of books do you like?",
2. "What did you study?",
3. "Which is your favorite season? Why?",
4. "What are you doing right now?",
5. What types of movies do you like?

II. Know how to combine general remarks with open-ended questions.

1. That's a nice handbag, where did you get it?
2. What an amazing buffet! Which is your favorite dish?
3. Fantastic turnout! Which of the lecturers is your favorite?
4. I love your costume. What are your favorite sci-fi movies?
5. I love your shirt. Where do you usually go for clothes shopping?

III. Talk about the current events

1. Hey, did you hear about that helicopter crash? That was pretty crazy.

IV. Draw on previous discussions
For example, their kid’s milestone, one of their projects, or some bad news that they shared with you.

V. Ask questions that are easy to answer.

What are you up to? meaning, What are you doing today? or What is your schedule for today?

"Remember, whoever you are talking to, you always have something in common. We all experience the weather, like good food, and enjoy a good laugh. When in doubt, just talk to them about what they are there for. For example, if you meet them at a bus stop, ask them where they are going. If they are from out of town, ask them about their life at home [1]."

"Take a mental note of some amusing things that you saw or heard throughout the day. For example, something funny someone said, a fun activity you did with your friends, or anything interesting. This can give way to future conversation [1]."

"Developing your interests. It's easier to start interesting conversations when you invest in developing your own interests. Be familiar with your interest so that you can articulate them. Broaden and deepen your interests by having the attitude that you are interested in everything. Another way to broaden and deepen your interests is to ask questions about others' interests. If your friend loves baseball, ask him which teams and players look good this year or ask him questions that clarify the league structure [1]."
