For some silly reason, this feeling, as you say, that one KNOWS when and if they are being stared at -- only came upon me intensely whenever I was on stage doing my thing! I'd look out there and everyone in the damn room would be looking right at me! How weird is that? Nothing I could do would chase 'em away. Strangest of all, when I was done, someone ALWAYS came up to me afterwards and handed me money.

I can tell you all, from own empirical experience: It is enough to make you paranoid!!
