Ask about their favorite activities
Find common interests. You might be interested in the same things. If so, then you can talk about the subject for hours. If your hobbies and favorites activities are different, express sincere interest in the subject and try to find out as much as possible about their favorite sport or music style.
Ask various questions
Your interaction should be active enough. Long pauses and silence indicate that you feel too nervous or uncomfortable with the person. Avoid this and start asking various questions. Think of your questions before meeting your date to make the conversation smoother.
