That Time I Was Blindsided by Desire

I never thought it would happen again, at my age and after all these years of self-control. But there she was, a brilliant young student with an energy that seemed to light up the room just by walking in. We went on what felt like harmless dates, but deep down, I knew better. She's sharp and smart; she could see right through me if she wanted to. One night, under the pretense of discussing my class material, we found ourselves alone and it didn't take long for something else to happen. It was just a moment, a lapse in judgment born from too much alcohol and too many memories from my past. I know better now, but how do you move on from that? It feels like part of me will always be stuck there.
