I know someone who allowed his wife to read his mobile phone. He did not have anything to hide. One day some female left a voice mail saying she liked him and wanted to see him again (without taking his name). She did not leave a phone number. The man just thought it was a wrong number...his wife did not. Now they are divorced. The ex wife thought he was having an affair and she got revenge on him by having a relationship with someone else. Someone may have put the voice mail on the phone to break the marriage.
