Well, today I stripped (really, I stripped) a friends PC to remove tobacco stained dust and confirm with trusty multimeter that the PSU no longer supplies... And found a replacement for pittance (which is good because she's broke), took my neighbour to hospital and back via, Oh treat of treats, Lidl - completely made her day despite not wanting any of the books I'd borrowed from a local charity shop and managed a 70 minute conversation with my mum without too much political discussion (we are, shall we say, diametrically opposed) and set a date to go back home for a couple of weeks. A good day.
