True story. A friend of mine hated Sheena Easton's "Morning Train". I found this out when he walked past my desk while I was listening to it. So whenever he'd leave his office, I'd call his phone and play the tape. Then I found out how to send it without calling his phone. So I did that.
Then...then I found out I could schedule a message to be sent.
Repeatedly.
As in EVERY. SINGLE. DAY.
Not for days. Not for weeks. For MONTHS.
He finally made friends with someone in telecomm and had them threaten to remove my voicemail access. Since it was the 90s and we still depended on voice mail, I had to comply.
Had that happened today, he might still be getting the messages. I have e-mail. And a second phone. And no one leaves me voice mails.
