I knew!

While evaluating a particular student/brother in the community, I could not but narrate this short story I heard sometime ago, to describe him best:

A family of tortoises went on a picnic and after years of walk, reached the spot and began to unpack their picnic meal.  However, they soon discovered that they forgot to get the salt. So after much discussion the youngest of them agreed to make the journey back home to fetch the salt.  However, his only condition was that they should not begin the meal without him. Once everyone agreed, he set out.
Months passed by and still when there was no sign of the youngest tortoise. The eldest then said that they start and he'll join in. So they opened their picnic meal.  The moment the lid was off, the youngest tortoise jumped out from behind a tree and exclaimed: "I knew you wouldn't wait for me! My suspicion proved right. I certainly am not going to get the salt!"

Some just wait for others to commit mistakes so that they can jump on them!
