I don't dwell upon this much -- most years I don't even think about it until a couple of days later. I have few fond memories; few memories, actually. His death sent our family into a financial hole that he could have prevented with better insurance. He was older, had heart trouble, and, as they say, was pretty emotional unavailable - a product of his day.
When he died, he had just finished rehabbing the attic of our home. We bought it two years before, and he tackled the reno with gusto. I remember him using hand saws. Stuffing insulation into attic eaves. Putting up drywall.
Dad updated a half bath, created a back room and put in a drop ceiling. I helped a lot as a nine-year-old would: grabbing tools for him, running up and down the stairs and watching him as he measured and planned.
Flash forward. Here I am, stuffing insulation, using hand saws, and measuring (although probably not as successfully). Not a bad legacy.
And, just a little bit, I envy the friends whose fathers are around to help them with a renovation
