Yeah, but my mother is incapable of managing an address book or using a smartphone with those types of features. In the past I told her to ignore every text message no matter how urgent or convincing it looks. Fortunately, she can't figure out how to read old messages so once a message times out and disappears from the screen she won't see it again.
