She just wants to dance around your ceiling. (Brachypelma is a genus of tarantulas from central America)
Last night, while going to the kitchen sink to fill the kettle for some tea, I endured one of the biggest frights of my entire life. A huge hairy house spider resting in that very sink. As a qualified arachnophobe I was rooted to the spot. It took my short housemate to obliterate the poor mite (!) with a paper towel and fling it in the bin. It is currently mating season for these monstrous arachnids, with males entering British homes looking for food, shelter and a significant other. Good times.
