Something unbelievable happened at the faculty of science in the University of Lagos.
A mathematics lecturer went to a class which he was scheduled to lecture but met the hall empty with no students present.
Rather than leaving, he picked up his marker and began to teach the empty hall, writing notes and speaking to thin air. The most shocking of all was after a part of the board was full, he dusted off the notes he wrote and continued writing.
We are as shocked as you. What do you think about this? See his picture below.
