Fire alarm

It was right the last minute of my teaching session when I said '明天见' (Míngtiān jiàn, meaning 'See you tomorrow'). So the fire alarm played the role of the bell to announce that the class was over. The very first time I ever had in the UK. ;-)

Lucky that I finished mine but those students and lecturers had to stand over there waiting to return after inspection. Often there were false alarms.

The building has been recently renovated.
