There are two kind of strangers,
Strangers to the mind and strangers to the heart.
Strangers to the heart are people whose existence you are aware of but further than that they can't offer you any familiar feelings.
Then you have the strangers to the mind, people who are like some
street decoration. Many faces with unknown names.
Those kind of strangers are the ones I like.
The reason behind this is that they are not able to cause any
disappointment at all.
They could be anything, and even if that turned out bad, they could not disappoint you, since you wont get the opportunity to know the way they are.
This is basically why I like those kind of strangers, those strangers to the mind.
