Forgot To Lock The Door

I recently got divorced and have been trying to figure out what I want from life now. One night, my Dominant friend visited unexpectedly, and we talked about our feelings and desires. He mentioned something I had never really considered before - that he finds it arousing when I don't follow rules or instructions. It was a revelation for me. We agreed to experiment with this dynamic one evening. That night came around quickly, and I did my best to stay true to the rules we set out. But then, later on, after we were done playing, in all the hustle of getting ready for bed, I completely forgot to lock the door like he had instructed me earlier. It was just a small thing, but I felt such guilt over it - worrying about what might happen if someone came into my apartment while we slept. And yet, part of me also knew that forgetting was exactly what he wanted from me in this context. So now, every time I forget something like that, no matter how small, I'm stuck between feeling ashamed and excited at the same time.
