I'm probably a bit younger than your father. I moved from a city I loved in the late 70s, and was never back again until 40 years later. The house I lived in was still there, but the people were never at home. Until my last trip there...
It was a wonderful experience. I hope to write about it some day when I have more time. Suffice it to say I got pretty choked up seeing my teenage basement bedroom for the first time in over 44 years, among other special places in the house.
Not much had changed in the room. Everything had changed in me. I live in different country and speak a different language most of the time. But for those 15 minutes in that room I was 14 again, with all the dreams and fears of a 14 year old. What a day.
