Ever since Josh was little, he's loved talking on the phone. When one of Mike's brothers would call, he would have Josh answer by saying 'bueno.' Now that Josh is old enough and fast enough to beat me to the phone, he answers it "hello, who is this?" His greeting may have changed but the way he ends his conversations has not. "Ok, bye, love you." If the person on the other end of the line is lucky, Josh will do this at an appropriate point in the conversation. The rest of the time, he will just do it whenever he feels like it. If it's in the middle of your sentence, or his for that matter, he will often times abruptly say his closing line and then hand the phone over. He's done. At least they know they're loved, right? Ok, bye, love you.
