You know how it is when you’re standing in the shower and you glance down and your eyes pass over the long, cobalt blue tendrils drifting near your foot and your brain zooms backwards into its nifty little visual data archive and – zing! – matches the tendrils to the image of the Portuguese man o’war that wrapped itself around your ankle in the water on Maui that one time?

But in actuality, you’re looking at clumped strands of silky thread from the insides of the plush, bright blue socks you were wearing before you got in the shower?

Yeah, me too.
