Its Labor Day. One of my favorite holidays as we celebrate the blue collar American worker and their contributions to our country thru labor and sweat. In the spirit of Labor Day, I had an amazing philosophical conversation w/ my baby girl about the value of hard work and how respect is given when it's earned. I told her, "Baby girl when you grow up, you get out there and dent the universe thru hard work and sweat. And always make sure you do it in a positive way with class, dignity and respect". She responded by poo'ing on me in this moment as she plays her favorite game, "Drum time on daddy's big head". It was a good talk.💯 #HappyLaborDay #TheJohnsons #GoodTalksWithDaddy
