Random Thought: Telling others everything

Why is that sometimes you are willing to tell a perfect stranger things you would not tell you own close friends or family?

Is it because you do not care what they may think or you know they will not use it against you.

It is strange how people may keep things secret about themselves to you, yet have no issues telling someone who is an acquaintance or a stranger everything and more.

Funny how people can be. Myself included.
