I felt a hand on top of my head begin to slowly pull off my balaclava.
A second person joined in.
I countered by digging my long sharpened-to-a-point fingernails
into their flesh knowing full well it would work.
After the initial pained yelp I heard:

    "Right! I know who it is!"

Maybe they did maybe they didn't.
Maybe subconsciously it was my subtle way of satisfying their curiosity
because these nails *are* my trade mark.

I walked out in a huff because my goggles could not be re-adjusted
without my nails being in full view and definitely giving the game away.
I went home (nearby) and came back in a complete change of clothes.
