Locks and their illusions only work if the agreement between strangers is kept. It must be the case because if they were so safe and effective then why do they make new models all the time. The fact is that is someone wants to open a lock and invade your privacy they will find a way.
My parents tell me of a time that sounds made up to me now in 2017. The fond memory of a time in Italy, where we use to live, where people trusted in their neighbors so much that they let their door and car keys on their locks. I mean isn’t it sad that now there are less and less places that continue to live with this kind of mentality, where people have faith in others and respect for their privacy.
