Today's Gratitude Item: Getting a relatively large number of cardboard box lids from the resource centre. Said box lids were needed for a practical that we get the students to do. They were supposed to bring their own cardboard / lid but I knew many of them would not manage to do this with less than 24 hours notice. It worked well. My colleagues might be a bit distressed to discover that the resource center is now all out of lids but this is one of those times that the early bird gets the worm (or cardboard box lids).
