Some may imagine that hurt feelings in a homeschool setting (like your own) will be less likely to occur because you are not in an institutional setting are among family. That expectation alone can make us susceptible to even more emotional upset because that is not the case.
We are broken humans in a broken world and ALL (including YOU, homeschool mom!) of us are going to say/do or not say/not do things that will upset someone. In families we can hurt each each other more because we are so close. Our teens also will still be cranky, scattered, forgetful, lazy, uncooperative and sometimes mean, albeit at a different (reduced) level than if they were in public school all day. We will also still be human and not respond in emotionally-controlled, rational, calm ways. When that happens, remember that we (sigh!) learn best from our mistakes. Billy Joel expresses that well in his song “Second Wind,” a favorite of mine (http://www.vevo.com/watch/billy-joel/youre-only-human-second-wind/USSM20100758) although the beginning of the video is a bit melodramatic.
