Our daughter would do similar kinds of things.
Early in her teens, she would do things like plug her nose and blow until air bubbled out her tear ducts. She would put Carmex into her eyes. There was a list of things I was going to post, but it felt wrong to do it, however anonymous the site.
I don't think about these things so much. It seems pointless to dwell on them, now. But I know what you mean SuZir, about that feeling that you know something, but you don't really see anything that glaringly wrong, after all.
And yet, you do see.
