One line you wrote was so true because it happened to me.
"He opened his dad’s office, expecting to see his dad, but he wasn’t there." My Dad died when I was between 4-5 years old my Mom and I used to visit the office building he worked at a lot. One time after he passed we went back to the office building I didn't put 2+2 together but she was there to clear out his desk. I recognize the office workspace immediately and when Mom started to open the door to his office I honestly thought I was going to see my dad.When Ronnie experienced the same thing all this came back to me.
