An Arm and a Leg

I'm not talking about the arms of my glasses here - I'm talking about the price of new lenses. My walk today was trekking from train station to opticians in Enfield and back, to get the best price for my complex lenses. I've stuck with the same frames, which are stratospherically expensive but have lasted me since 2006. Most of the walk was residential streets. How I managed to take care of four children, a husband, a dog, a business AND walk one mile from home every day whilst producing a piece of art and a blogpost every day, the previous time I gave myself this challenge, baffles me.
