Common chair

The title is a double entendre. It is a typical chair seen throughout the University. It is also a chair sitting in the Common. Why? Who knows? There was a tent there for few days so the student union could have a welcome back event for the winter term. Perhaps it is a stray from there. Or, it may have been relocated from the food court in the nearby Student Centre. Wherever it came from it was an uncommon sight in the Common and I thought that would make for a curious blip.
