Why is it easier to talk to complete strangers than it is to talk to somone you know?

I was on fluther once and my boyfriend asked me how come I could ask complete strangers something about my personal life. I didn’t really have a good answer to that, and I was wondering what other people thought of it.

To clarify, it’s not that I don’t ask real people. He just wonders how I can ask strangers personal stuff. His example was, “you wouldn’t walk up to a stranger on the street and ask them, so why is it easier on the computer?”
