what is so unusual about it?  It looks so ordinary, you'd think
nothing was wrong with it and in fact, nothing is wrong with it.
It IS unusual, why?  Study it. Think about it and you may find
out. Try to do it without coaching.  If you work at it for a bit,
it will dawn on you. So jump to it! Try your skill at figuring it
out! Good Luck - Don't blow your cool!
