Struggling to walk the walk with my kids watching

So I lost my cool at someone in traffic yesterday and my kids heard me say some things I'm not proud of. My oldest asked me why I was being mean when we talk about treating people with kindness. That hit different coming from your own kid. I apologized to all of them and we talked about how even dads mess up and have to ask for forgiveness. It's humbling but I think it was a teaching moment. Anyone else have to check themselves in front of their kids and readjust?
