Working at the weekend...

...is tiring. But also strange. My weekends usually consist of such an intense level of bugger all that it's quite standard for me to get to half past three on Saturday and not really be sure what I've done for the last five/six hours. I've stopped questioning it, so I take that as acceptably dead time - but that means that now I've plonked myself back at home (and discovered that it is in fact half past three), it feels like I've somehow managed to do a load of work in negative time. Saturday's only just begun, clearly - but it also included six hours of library time? The sums don't add up...
