I do this even for "friends" and family whom I haven't heard from in forever if I wonder whether their address book has been hacked and that's why I'm hearing from them now. And I rarely ever open an attachment or a URL included in an email unless I'm expecting it. I'd rather be "rude" than sorry.

I've been on the internet (properly known as the World Wide Web, or www) for 20+ years and have been disrupted only twice in all that time using these (and other) precautions.
