As expected. Given the kid's actions and public comments, I have a strong suspicion that he was neither respectful nor polite.
If the student was neither respectful nor polite, you would assume that the wife would’ve saved the message to show her husband when he came back from work that evening, no? The husband has been interviwed by several DC-area radio stations today, so why not the wife? She’s the one involved in this phone call drama, so why doesn’t she defend her actions and/or talk about the tone the student used in the message he left at their home?
