If ever you find me in a position wherein I appear to be unaware of my surroundings and unaware of the people in my surroundings such that I am an annoyance and causing frustration to those near me, just hit me. Not hard. And not in the face. Maybe just a firm slap on the neck just below my ear followed by a forceful finger pointing. Or perhaps just a forceful finger pointing accompanied by a stern look of reproach. Maybe not a stern look of reproach, but rather a sympathetic look of reproach. Consider a light patting on the back or better yet a kind circular rubbing motion almost massage like. A hug, Just give me a hug. But not too hard.
