Ditto to that, although I've never tried the cap before. Thanks for the suggestion. I do something similar when I'm driving; I always have the visors down as low as I can get them and still see the lights, etc.

For me, hands are even harder than some other objects. Perhaps it's an emotional thing, perhaps not, but having hands move near me, particularly quickly, always makes me feel threatened. And those people that think it's funny to clap their hands in your face to startle you or something similar are likely to see a monster they didn't expect if they try it on me. Why? Maybe because the content can seem so "hazardous." I guess it doesn't really matter in my case; bottom line is, I don't let people do it around me without a serious talking to. Of course, in the case of my two year old doing these things to me, hands always seem to end up in my face, so perhaps that's part of why it's very annoying to me right now.
