Profanity isn't shocking anymore. It's not edgy or sassy or hip or rebellious. It's just a sad, tiresome example of our shrinking vocabulary. Thanks, Twitter. People swear when they have nothing to say, but they want to talk. My feeling? You're not getting paid by the word and you're not a sailor. So keep it simple.
It's okay to feel frustrated with your children. It is okay to be angry at not being able to control a situation. We are all humans, including our kids, and hence, we are not perfect. We're deeply flawed creatures. A part of being flawed is recognizing that we may have angry thoughts related to our children when we are having a bad parenting day.
