Horsefly/Cleg

When I was on a school trip at Tal-y-Bont near Harlech, in 1966 I had something bite my knee, it went septic and I spent my summer in Wick being treated with various crap, until my Granny put a hot poultice on it (ow ow ow) which cured my knee. I still have the scar. Fast forward to Tuesday last, painting my new shed with David helping, I looked at my leg and there was a fly biting my leg, and another one just starting on my other leg (I have two). Now I have two swolen ankles. Damn those flies/clegs.
