I bought new socks a couple of months ago, in the winter. I got rid of my old worn out socks and bought a few packages of new crew length socks (longer than ankle socks, but shorter than knee socks) in various colours. I bought black ones, charcoal grey ones, white ones, pale blue ones, mid-blue ones, and navy blue ones. About 12 pairs in all. And now, in May, all I can find are the mid-blue ones. And I seem to have more pairs of the mid-blue ones now than when I purchased them.
How could that be? Shouldn't the dryer just be eating one sock of each colour, leaving me with one black, one grey, one white, one pale blue, etc.? But no. There are about 4 or maybe 5 pairs of mid-blue socks in the clean laundry.
I've thought long and hard, and I think I've figured out what's going on.
Seasonal colour transition.
No, really. It all makes sense now. The socks are reacting to the lengthening days, and pigments in their skin are changing to camouflage them against the more colourful summer clothing palette.
It's just nature at her most resourceful. After all, I do live in the northern hemisphere, where wildlife has evolved seasonal colour variations in order to hide themselves from predators (e.g. hares) or prey (e.g. foxes):
There's a Nobel prize for biology, right?
