Aaargh! Horribly stressful day - I was supposed to be giving a mineralogical workshop online via Zoom. But we had a powercut this morning in Mull, while I was making final edits to my presentation. About half of it got corrupted without me noticing. Then I overwrote my backup copy with the corrupted version. 😭 😭 😭 Event cancelled and will be rescheduled. #TwoBackupsIsNeverEnough #MoreBackups #Aaaargh
