If you want to start talking to a guy you should look for something you both have in common, such as a hobby or interest, and start the conversation with that.

Instead of asking yes or no questions, try asking questions that require more than a one-word answer,also ask him about the things of his passionate.

Ask him with a friendly attitude and a smile. Don't be afraid to initiate the conversation.Start with light topics such as weekend plans or current events,ask about the things which you want to do in free time.

Remember, the most important thing is to be yourself and be confident. Don't worry too much about making a perfect first impression. Just be natural, and the conversation will flow.
