They are knobbly and hairy and have frightened many postmen (and the occasional postwoman) delivering early-morning parcels over the years. The right one is scarred from various accidents falling-off motorbikes. They never, ever, usually see the sun. My knees.
But today I'm so grateful for a purchase I made on holiday - an end-of-line bargain at the Hawkshead shop, Ripstop 2-in-1 Trousers. The sheer joy of getting home hot'n'sticky, unzipping these things and revealing me knees to the air. One of the few pleasures this heatwave has held for me.
