My boyfriend leaves Nickelodeon on or Cartoon Network for him during the day when were at work, and if I'm working late and call my boyfriend, Rocky will sometimes hear my voice and start looking around the room for me
So then he'll put Rocky on the phone. We don't call and leave messages, because we only have cell phones. My boyfriend did want to leave Nextel in his cage though so we can beep hiim through-out the day, but then we'd have to get another Nextel and we already hate them so we decided against that.
