I'm meant to be putting up some net curtains at the moment. A simple enough task, and one that's probably not taxed even the simpler minds over the last few centuries.
But we just can't work the frigging thing out! Resorting to the internet hasn't helped - the task must be so fracking easy that no-ones even considering posting a "how to" on the web.
Its the same stoopid situation as coin-operated shopping trolleys - designed to be used by even the most imbecilic of imbeciles, and it took me about a decade of shopping after my teenage years to work out how to get one without handing a quid to someone returning their trolley (and Ms Starbuck still can't do it!)
