People are afraid of somebody else they never know before. They might think that why should they care about strangers. Nobody knows strangers may become your friend someday.Either the one who you just unintentionally met, the one you want to be in a relationship with, or even the one who already known you, but you had never talked to. We never know what will happen if they were met each other. Their life would be change temporary or forever? No. It’s rely on your decision. That’s why we called them “Recognisable Strangers”
