Invasion of Privacy

Does anyone understand the word PRIVACY?

According to the dictionary, Privacy = freedom from unauthorised intrusion

So everyone, pls tell me if i'm wrong.

Reading through another person's email or letters, or searching through their personal belongings without the owners' permissions is considered as invasion of privacy, no?

I mean, the website asks for your password before logging in with a reason, right?

I am utterly upset when I got to know that someone close to me has just violated my privacy.

From my point of view, so long as you have violated my privacy, you don't respect me anymore.

Enough is said.
