People fear being taken advantage of by others.

    Stranger Intervention, is a relational wedge that reflects a way to initiate a conversation with a stranger in public without introducing themselves. Therefore, in my opinion a relational wedge needs to be applied with careful because you never know who could hurt you or who has bad intentions. Moreover, the real reason why I do not like to be a petitioner is because the granter may be in a rush or even in a hard time and I would not be the person who stops its time.
    I think that most of the people when they use public aid are qualified as a "persuaders" because they find the way to manipulate you by taking advantage of your time and maybe of something else too, for example robbing your wallet.
    In conclusion, the Public Aid needs to be required to the right person, in other words, choose the person who looks like he or she knows. Anyway, I prefer not to ask for help or being asked on the streets because i could turned into something bad. Therefore, my motto is always "Do not trust everybody".
