1. You don't need a conversation, you just want to *inform* (get 1 milk too)
2. You know the recipient is not available to talk...church, meeting, driving, sleeping
3. You want to send a mass-message to your phone book (Happy Thanksgiving from Butthead)
4. You want to tell someone that you need to talk, but can't now, could they please call later
