Ask Personal Questions

Use this trick if you need to get someone to like you immediately. It also works the other way around. Tell something personal about yourself to earn a person's trust. But don't spill your guts at once. Give it out gradually. Repeat your interlocutor's body language. If both repeat each other's movements and facial expressions, it means that the contact is established. That way you can even check how well the conversation is going. Try to sit a little differently and see if the person does the same.
