"Dad you taught me everything from how to walk to how to be a man and for that I thank you," he captioned an Instagram pic. "Thank you for getting up at 4:30am for work and not coming home till 7 pm everyday for more then 20 years just to keep food on the table, and for us to have a great life. I'm the man of the house now and I promise to hold everything down. I promise."
