It's so easy to say anything that comes to our mind. Often what comes out of our mouth is sensitive to how others feel. We don't mean to hurt anyone, but we end up doing just that. Of course, sometimes we get misinterpreted too. This can happen easily at home with your own family. I see this as a form of self-indulgence. What can help is to see Christ in every person. Such an awareness keeps us from saying anything that might provoke or offend others.
