This e-mail is for trying to reach someone who's been out of touch for a considerable amount of time.
Anybody out there? Hello! I know you're out there somewhere, I can hear you breathing! Seriously, I'm wondering why I haven't heard from you in such a long time. E-mail is supposed to make it easy to keep in touch. Did I do something wrong? Do I have bad breath? Needless to say, lots of things have been going on in my life, such as <tantilizing event>. I'm willing to bet just as many big things have been happening in your world. I'd love to know what they are. So drop me a line already, will you? If I don't hear from you, I'll just assume you've been given a new identity by the CIA and been whisked away to Bora Bora. But please let me hear from you.
