Like many non-heterosexuals -- at least of my generation -- I think it's sometimes difficult to find things to talk about with my father. He (like many of his generation) grew up in the most severe period of the Dark Ages -- a period extending from roughly the Second World War to the current era -- a time when homosexuality was not only taboo, it was barely even acknowledged, and masculine/feminine stereotypes hardened in the United States and were exported around the world for mass consumption. As a result, homosexuality tends to be something that's 'accepted' with a lot work, but never really understood or embraced.
So we sometimes struggle to find common ground. In my own case, I can't pretend to share my father's political views and I'm no longer really interested in sports, unless I happen to catch a game or two of the Penguins when they make the Stanley Cup finals. That's why I've been so happy that my father and I discovered gardening around the same time, roughly ten years ago, when we each moved into our new houses.
My father spends hours in the garden now, planting and trimming and weeding and arranging, all the sorts of things that all gardeners do. He and my mother (who has less patience for the tedium of gardening) moved into a house that already had a beautiful infrastructure, which he has managed to maintain as the years have passed while putting his own signature onto the landscape.
So now in lieu of politics or sports, we discuss the garden; what's thriving this year (we both have a fondness for certain types of sedum, and he has a real talent for roses) and what isn't (the clematis).
In this way a new and better relationship is born when an old one has been set aside.
