FOR a long while, my father’s way of coping was to walk quietly from the room. He doesn’t remember this. I do. I can still see it, still feel the pinch in my chest when the word “gay” came up — perhaps in reference to some event in the news, or perhaps in reference to me — and he’d wordlessly take his leave of whatever conversation my mother and my siblings and I were having. He’d drift away, not in disgust but in discomfort, not in a huff but in a whisper. I saw a lot of his back.

And I was grateful. Discomfort beat rejection. So long as he wasn’t pushing me away, I didn’t need him to pull me in. Heart-to-hearts weren’t his style, anyway. With Dad you didn’t discuss longings, anxieties, hurts. You watched football. You played cards. You went to dinner, you picking the place, him picking up the check. He always commandeered the check. It was the gesture with which he communicated everything he had trouble expressing in other ways.

But at some point Dad, like America, changed. I don’t mean he grew weepy, huggy. I mean he traveled from what seemed to me a pained acquiescence to a different, happier, better place. He found peace enough with who I am to insist on introducing my partner, Tom, to his friends at the golf club. Peace enough to compliment me on articles of mine that use the same three-letter word that once chased him off. Peace enough to sit down with me over lunch last week and chart his journey, which I’d never summoned the courage to ask him about before.

It’s been an extraordinary year, probably the most extraordinary yet in this country’s expanding, deepening embrace of gays and lesbians as citizens of equal stature, equal worth. For the first time, an American president still in office stated his belief that two men or two women should be able to marry. For the first time, voters themselves — not lawmakers, not courts — made same-sex marriage legal. This happened on Election Day in three states all at once: Maine, Maryland and Washington. A corner was turned.
