A Secret I Keep Quietly Alone

I've been married for over thirty years now. Sometimes when my husband's asleep and the house is quiet, I think back to a night in my late twenties, just after we got married but before life took over with jobs and kids. We were young and everything seemed possible. That night, alone at a party we both attended, I had an encounter that felt like it shattered all that idealism we held onto so tightly. It was nothing graphic or even described here, the details don't matter anymore, but just knowing there's something buried in my past that feels so separate from who I am now makes me feel oddly lonely. Even if nobody ever knew, it's one of those things I keep to myself.
