The 18-year-old Modern Family star posted on his Instagram page Sunday a photo of the two drinking milkshakes.
“This has been the toughest week of my life,” he wrote. “My Dad was the most kind hearted, loving, hard working, determined, and funny man I have ever known. He was like a super hero, he had the ability to get the best out of you day in and day out.”
“I’m gonna miss your hugs,” he said. “I’m gonna miss your advice. I’m gonna miss your smile, and I’m gonna miss your laugh. I know you’re looking down at us right now giving us the green light to move forward. I miss you Daddy. I’ll love you forever – Your youngest.”
