Messed up logistics
I have had to restructure my schedule for today twice now.
Once to attend a county youth orchestra reunion curry (as one of my resolutions is to get back in touch with people I've lost contact with, I can't really not go) which means I need to get a train at 6, thus removing 4 hours I had planned to do some work in.
The second time is due to the fact that although I got to bed quite early (not that long after midnight) I did not get to sleep until after 4. So I got up 2 hours after I'd intended to. That meant I have had to postpone my planned trip onto campus.
On that subject, I need to get ready if I hope to get on campus, do what I need to do and get back here by half past 3.
