Inverted

This is underneath a staircase in Hunter Hall at Glasgow Uni.

I took it whilst I waited to go into the exam hall today. It went ok I think (hope), no long periods of total blankness at least.

I had to have a tooth extracted afterwards (the two things were unrelated) - I haven't had a tooth out since I was a child - there's more blood involved that I remember.

I'm so hungry.
