"Security does not mean privacy."

I sometimes stumble when I try to explain how security and privacy are different and usually I'll just explain with examples. I like these examples here.

When browsing a website which uses HTTPS, anyone viewing your traffic will be able to tell not only which website you’re viewing, but for how long and how frequently. (NOT really private) Though the content between you and the website is encrypted, (and so secure) the fact that you’re connected to the website’s IP is to be considered public knowledge.
