Well, I'm not sure I've given this one enough time, but I'm about ready to tackle the next memory.

I was about the same age. My sister and I slept in the same room. I couldn't fall asleep, and I don't even remember what I was thinking about but I started making kissing sounds with my mouth. I went on for quite a while, so that my sister had to call me out. I imagine it was a pretty uncomfortable situation for her. And I - I've got to guess, if it wasn't from the start, towards the end it turned into an automatic action, a light exercise for my mouth to calm myself down (like I sometimes sing in bed). Although I don't remember 100% clearly at this point, of course.

This haunts me mostly, I think, when I think about another of my inappropriate actions, so it's kind of a cascade effect... And probably on the topic of unconscious behaviour, especially in teenagers.
