My Windows laptop. Someone was giving it away and I thought it'd be handy for when you need to use Windows rather than Apple software (Indian visa application website, I'm looking at you). So there's that one time where you think "Oh, I wonder if this will work better on the other laptop?" and you fire it up (having first located the charging cable because obviously the bastarding battery is flat). But wait, what do we have here?
"Installing update 1 of 946"
Where is the NOT NOW, NOT FUCKING NOW I'VE GOT A TRAIN TO CATCH AND I NEED TO DOWNLOAD THE TICKETS button? Nowhere to be found, that's where, because - sanctimonious arsehole that it is - it thinks these updates are for your own good. Bastard.
The tumbledrier is a wanker too, what with its "filter blocked" warning light. On it pops and you drag out the filter to find a hair so microscopic it's invisible to the Hubble telescope let alone the human eye. Other times, however, there's enough hair in it to knit your own woolly mammoth and not so much as a blink from that fucking light. Bastard.
The printer has long since been banished under the sofa as punishment for its myriad crimes: not connecting, pretending it hasn't got any paper in it, complaining its cartridges are only 98.5% full etc. etc. An absolutely bastarding bastard.
Oh, I nearly forgot the bathroom extractor fan. It broke and one of the outside flaps fell off so it serves no purpose other than being a hole in the wall that makes the bathroom - and the entire house, if you forget to close the door - colder than a penguins knackers. Bastard.
