That blue cap came from a sun-block bottle, shaken by a pony-tailed girl over shoulders already too plump and pink, which would hurt her next day, though she didn't care.
Thus I forgo some of the more youthful pleasures of Bangkok (I have already seen enough pony-tailed 60 year-old men with their tiny, leggy ‘girlfriends’ and I feel no need to buy a fake watch).
