Flood in the office

I am not sure if it is correct to call that disaster a flood, for the only thing which was hit in the city was the interior part of the Department of Mechanical Engineering. Last Thursday, suddenly a rain storm started in mid afternoon, and the water started to enter the building from the roof, but not from the ground. The consequence is seen in the photo:

All the undergrad and grad students where sweeping the ground to wipe the water. Till here I do not care, what is making it so memorable is what happened to my office:

you can see that the roof tiles have fallen down and the glass fibers are exposed.
