I have this terrible habit of multi-tasking.
I was reading the newspaper while walking to the canteen.
"Thud"!
My head knocked the door at the entrance.
The students behind me giggled.
I turned around and smiled at them bashfully.
For some unexplainable extreme extend of stupidity, I continued reading the paper.
I turned at the corner and misjudged the degree of that corner and another "Thud"!
The students were guffawing this time.

I soothed my head and smiled at them.
It WAS very funny.
