Three at one Time

My colleague named Sajid has gone out of office. I noticed that he was reading three books at one time.He is really a book worm like guy in Gujrat University.

By looking at three opened books, a thought wave just crossed my mind that whenever you are involved in some tricky problem solving, you yourself do not know what changes are being brought about in your vicinity.

In such situation your mind just plays with problem solving abilities of mind and forget every thing around you.
