Would you talk to people whom you meet for the first time?怎么

Well,naturally I have no problem talking to people whom is introduced to me for the first time.There are also many cases that I need to talk to total strangers,basically whenever I go out to shop or to dine.I am open to casual conversations during a trip etc.,with someone I happen to meet out there.But I usually stay alerted not to reveal too much of my information.I prefer to make friends through my other friends or within my "circles" so that I already get to know something about them when we meet for the first time.
You cannot do it this way and remember what other people say.Don't u have the answers in ur own mind?Just try to write them down and translate into English.
