This is what happens if you run into the strong Mediterranean surf pounding the beach to help your mother get out of the sea because she can’t because the undertow is too strong and she keeps getting knocked over and you’re really worried so you run down to the shore and wade in without taking off your sarong or sandals and you’re wearing sports sandals you know the kind with velcro fastenings you’re supposed to wear for sports and being active and stuff only apparently you’re not supposed to wear them in the sea because as soon as they get wet they transfer mysterious blue dye to the soles of your feet, which you don’t notice at the time because you’re too busy being happy your mum is not drowned but later when you put your feet up after dinner you realise that the soles of your feet are, in fact, bright blue, stained with a dye which absolutely will not scrub off and a week later is still there, though thankfully starting to fade a bit now so I look a little less like an alien though you’d think Clarks might bother mentioning it when they sell you the sandals, which they don’t.
