Talk with a stranger means you have to talk to that person whom you do not know and have not met him/her by any means earlier, neither you have seen him/her nor you have about his/her past information, which means the new person is introduced in front of you and you have to talk to him/her properly so that the person does not feel disrespectful or gloomy after meeting you or chatting with you. Therefore, talking to strangers is quite strange during the first time but as soon as you cope up with that person smoothly and nicely with your conversations, you will get to create interest in that person sooner or later. Thus, talk to strangers is about the random talks that you do with them when you meet then and talks about the spontaneous things which are not official and not confidential.
