What makes a good conversation starter?

2. 
3. Open-ended: A broad question typically generates a far more engaging answer than a close-ended one.
4. Non-routine: Breaking out of the standard weather and job-related questions will jolt the person you're talking to out of autopilot. You'll also make yourself more memorable.
5. Professional: Some topics are more suited for your friends and family than strangers or near-strangers. Your questions should never make your conversational partner uncomfortable.
6. Relevant: If you can, start a conversation about something timely or specific, such as your location, event, industry, jobs, or current interests. The other person will find it easier to contribute.
